Karbonn A7 specifications
Karbonn A7 Review
Another day, another budget Android phone. Google’s operating system seems to have taken off in the Indian region as the market is now flooded with Android devices and it shows no signs of slowing down. Karbonn recently announced its A7 smartphone that aims to pack a whole bunch of goodies in a budget. However, as we’ve seen with previous phones we’ve reviewed, there are certain trade offs that users are forced to live with. Does the A7 follow that norm, or is it an exception to the rule? Let’s find out.
Design and Build Quality
The Karbonn A7 looks like a device that was heavily ‘inspired’ by HTC’s One Series. In fact, to say that it was inspired may only be an understatement. For the user, though, this is nothing but good news, as low-end Androids have more often than not been cheap plastic devices and the A7 looks nothing like that. The phone has a nice smooth matte white finish at the back and a silver rim surrounding the screen in the front. The 3.5-inch screen is a fingerprint magnet and has a low resolution of 320 x 480 pixels. Below it are three backlit capacitive buttons and one physical button.
Volume rocker on the left
Button mapping is slightly different as the physical button takes you to the Search feature instead of the expected home screen. There’s a VGA front camera included as well. Moving on, the top has a power button and a 3.5-mm headphone jack while the left has only a volume rocker. On the back, you'll find a 5-megapixel camera and a dual LED flash. The microUSB charging slot is located on the bottom edge.
The device weighs 120g and feels sturdy. The A7 easily beats a lot of the devices in its price range as far as design and build are concerned. In fact, it’s got the looks to take on the likes of Android devices that are priced in higher brackets too, making it a benchmark of sorts for competing devices.
Features and Performance
Interface
The A7 is powered by an 800 MHz processor and has 512MB of RAM. It runs on Android Gingerbread 2.3.6. Manouvering through the various home screens and menus is pretty smooth and lag-free. Memory intensive games and apps slow down the overall functionality a little though. The interface isn’t too different from the stock ones we’ve seen in the past, but a few tweaks such as power control options in the notifications dropdown, customizable animations and additional widgets give the A7 that extra bit of functionality.
Sub par display
In our benchmark tests, the phone notched up a Linpack Single Thread score of 20.3 and an AnTuTu score of 2232. This was a tad lower than the Andi 4D that we reviewed earlier, which runs on a 1GHz processor.
Media
The media UI doesn’t offer anything particularly unique in terms of looks and file format support. Video format support is limited to H.263, H.264, AVI, 3GP and MP4.1080p and 720p video didn’t play on the device. Music via the headphones is good and the bass has a nice amount of thump. Also worth mentioning is that the inbuilt FM Radio worked pretty well on our train journeys, and the speaker is loud enough to fill a small room.
Heavily inspired by the One Series
The 3.5-inch screen is large enough for personal viewing but the display quality leaves a lot to be desired. Colours appear faded and the screen isn’t particularly bright or sharp. That’s the kind of price-related trade off you’ll have to live with.
ZOTAC GeForce GTX 660 Ti AMP! Edition Review
Design and Build
ZOTAC sent us the AMP! Edition of the GTX 660 Ti which comes with higher clocks for the memory and core, out-of-the-box. Apart from the typical packaging which highlights the important features of the card, you also get Borderlands 2 along with it. Nvidia is bundling Borderlands 2 from its side for a limited period, but this is only in the US and Europe, so in India, it’s ZOTAC who’s taken the initiative. This is great value added right here. The card is actually deceptively small and is about the size of a GTX 560. This makes it super easy to install in most systems, so props to ZOTAC for the great design. It’s a dual-slot card with two DVI ports, HDMI and DisplayPort.
A handsome looking card
The GTX 660 Ti also debuts ZOTAC’s new cooling system called ‘Dual Silencer’. The setup consists of an aluminium heatsink with copper pipes to dissipate heat more effectively, which is then cooled by two fans. It’s an open cooler, in the sense, the hot air is not channeled outside the case but rather inside. This shouldn't be a problem considering the low TDP (150W) of the card and the smaller 22nm fabrication of Kepler.
Good set of connectors
You’ll need two 6-pin PCIE power connectors to power it up. In case you run short, you’ll find adapters bundled in the box along with a DVI-to-VGA adapter. Overall, ZOTAC has done a good job with the GTX 660 Ti and we especially like the tiny footprint it leaves inside your system. That and the fact you get a copy of Borderlands 2 when it launches makes it a very compelling package.
Features
Nvidia’s aim for the GTX 660 Ti was to give gamers the power of its higher-end cards like the GTX 670 and GTX 680 but at a reduced price. In order to do this, Nvidia has made some cutbacks in the specifications, but thankfully, haven’t neutered it too much. In fact, the only thing that’s changed is a slightly narrower memory bus of 192-bit instead of 256-bit and fewer ROPs (24 instead of 32). The rest of the specifications are identical to the GTX 670, so you get 1344 CUDA cores running at 1033MHz and 2GB of GDDR5 memory running at 1652MHz (6608MHz effective speed). The core and memory clocks are overclocked since this is the AMP! Edition from the stock 915MHz for the core and 1508MHz for the memory. This is still a lot of horsepower and the reduced memory bandwidth shouldn’t really affect the performance by too much as long as you game at 1920 x 1080, i.e, on a single monitor. Nvidia recommends a 450W PSU from a good brand, so chances are you won’t have to upgrade your PSU for this card.
Better power efficiency than the higher-end cards
Since this GPU is based on the same GK104 die, you get all the new features that Kepler offers. We’ve covered this in our previous reviews, but in case you missed it, here they are once more. The new features include GPU Boost, Adaptive V-Sync and new Anti-Aliasing (AA) models. GPU Boost is similar to Turbo Boost, in the sense, the card will dynamically increase the clock speeds and voltages in a game, if and only if it does not go beyond the set TDP. For instance, if there is an intense battle scene in the game which demands more shader power, the built-in algorithms will automatically check the current power draw, temperature, voltage etc. of the card and accordingly increase only those parameters that can be pushed. This keeps changing as you play the game and is built into Kepler itself, so it kicks in by default. Adaptive V-Sync can now be found in the Nvidia Control Panel and what it does is, dynamically toggle the V-Sync state depending on the frame rate. For instance, if you’re getting more than 60fps, then V-Sync will be on to avoid screen tearing and if it dips below 60fps, then it switches it off to avoid stuttering. The two new AA modes (FXAA and TXAA) are said to offer similar quality levels as MSAA, but without the huge performance hit.
So far so good; the GTX 660 Ti seems to have all the ingredients for a powerful high-end card but with a lower TDP and smaller form factor, thanks to ZOTAC’s design.

Sony Xperia ion Review
Design and Build
Sony has ditched the plastic chassis and gone with a more sophisticated look with the ion. The phone is encased in metal with plastic bits on the top and bottom for the radios to function. The curved back and smooth finish add some flair to an otherwise blocky design. Dimensions and weight wise, it’s nearly identical to the Xperia S so you won’t notice much of a difference. Sony has fitted a slightly larger 4.6-inch screen on the ion as compared to the 4.3-inch one on the Xperia S. It still has the same HD resolution and is an LED-backlit LCD with scratch-resistant glass.
Sleek and stylish
On the front, we have the 1.3MP front facing camera along with the proximity sensor, notification LED and ambient light sensor. Speaking of the latter, Sony hasn’t included an auto-brightness option in the settings so even though this sensor is present, it’s pretty much useless. We don’t know what possessed Sony to make this decision, but yes, their brand new flagship does not have auto-brightness! This is also the only high-end Xperia to have four capacitive buttons instead of three, and none of them work well. First of all, the labels don’t light up themselves; instead we have four horizontal dashes that do, which is useless, since in the dark you don’t know which label you’re actually hitting till you're quite familiar with the phone. That’s not all; the sensitivity of the capacitive buttons is very weak, just like the Xperia S. You’ll find yourself pressing each one a couple of times before your touch is registered, which is extremely frustrating.
HDMI onboard
The microUSB and HDMI ports are covered with a flap on the left while the power button, volume rocker and camera button sit on the right with the 3.5mm headphone jack sitting on the top. We came across another annoying design flaw with the power button: it’s a little bit too recessed for you to access it comfortably. Also, the extra piece of metal just above the button with the ‘Power’ symbol on it actually feels like the power button. The rest of the buttons work just fine though. The phone's grip doesn’t feel reassuring in your hands and if you’re not careful, if will slip out. We do like the fact that the chassis is metal so it’s a lot more durable.
Features
Interface
This is Sony’s first high-end smartphone to ship with Android Ice Cream Sandwich out-of-the-box but due to their own skin, there are plenty of hiccups in overall performance. You’ll notice slight lags when browsing through home screens or apps right from the get go. And it’s not like the phone is a slouch; it’s powered by the same Qualcomm Snapdragon MSM8260 SoC used in the Xperia S.
Same as before
At 1.5GHz, the UI should be absolutely fluid but sadly it’s far from it. Nothing has changed with the interface and it’s the same one we've come across on all Xperia phones of late so we won’t get into that too much. Since this is ICS, they have changed the way you add widgets to the home screen slightly. Long pressing on the home screen brings up a little icon on the upper left hand corner, from where you can change the theme or wallpaper.
Media
The media player is the new revamped one we’ve seen on the new NXT line of Xperia phones but once again, since this is ICS, Sony has changed the graphics and layout slightly. The music player widget now also displays album art and Sony has added a lock screen widget as well, allowing you to skip songs without having to unlock the screen. You get a 5-band graphic equalizer along with a bunch of presets and some other audio enhancements. The sound quality is very good though and the bundled headset provides good ambient noise isolation. The speaker on the other hand is just plain horrible for anything other than notification tones. Even with XLoud on, the sound is flat and very weak and the EQ is no help here.
Speakers are not very good
The video player is a little disappointing since you only get the stock Android player, which only plays MP4 and WMV. You do have options to stream video via DLNA though. The Xperia ion handles 1080p videos like a champ without skipping a frame. HD videos look especially good due to the densely packed screen. Colour reproduction is accurate and colours are rich and well saturated, without going overboard. Format support can be expanded via third party players from the Play store.
Connectivity
The Xperia ion is a quad-band GSM and quad-band 3G phone with support for advanced 42Mbps HSDPA and 5.8Mbps HSUPA speeds. We also have the usual assortment of Wi-Fi ‘n’, Wi-Fi Direct, DLNA, NFC and Bluetooth v2.1. Just like the Xperia S, we have support for the new GLONASS navigation system, along with GPS. Sony has cut the internal storage down to 16GB but has thrown in a microSD card slot. There are plenty of Internet and social apps bundled along with the phone.
Good connectivity options
TrackID lets you identify songs, which works well but is not as feature rich as SoundHound. Music & Videos aggregates all the videos that your friends have ‘Liked’ on YouTube and even new videos that you have subscribed to. AppXtra is a little app store created by Sony and Recommender is something similar that shows you apps that have been rated highly by other users of Xperia phones. Tags lets you manage NFC data picked up by the Xperia S, which can be shared to other phones with NFC as well.
Misc. Apps
Sony bundles extra apps like OfficeSuite (only for viewing of Office documents), Media Remote (which lets you use your phone as a remote control with Wi-Fi enabled Sony TVs), WisePilot, NeoReader, Stopwatch, World Clock, Notes, etc.
Camera
Sony has used the same camera sensor as it did with the Xperia S so you get a 12MP shooter with an LED flash along with other features like geo-tagging, touch focus, face and smile detection, 3D sweep panorama, image stabilization and more. The camera is great for outdoor photography and macro shots are really good as well but just like before, indoor pictures are not really the best. There’s a lot of colouration and noise visible in dark areas, even if you use the flash.
Camera UI is simple to use
The Xperia ion can record video in 1080p with continuous auto-focus. While captured video has a solid framerate, it takes time for the auto-focus to kick in and re-adjust. We wished it was a bit quicker as you have to wait for a few seconds till your subject is in focus if you’re moving. The video can be viewed directly on an HDTV via the HDMI port.
Very good at macros
Battery Life
Sony has bumped the battery capacity up to 1900mAh, which seemed like a good move, but doesn’t really help a lot. While we managed to get a decent 6 hours and 40 minutes in our video drain test, in real world usage, the phone will just about last you a day or perhaps even less if you’re on 3G.
Verdict and Price in India
I guess ‘old wine in a new bottle’ is how I would describe the Xperia ion. The phone is essentially an Xperia S with new overalls, a larger battery, slightly larger screen and a microSD card card slot. And for just this, Sony is asking for Rs. 36,000! That’s a good six grand more than the current price of the Xperia S. Like I said in the beginning, the ion just doesn’t have any place in the market right now, it’s a phone that should not exist. Sony is trying to flood the market with variants of essentially one phone and in doing so, is just causing chaos and confusion. Very soon, they will be launching the Xperia SL which is essentially an Xperia S running at 1.7GHz instead of 1.5GHz.
Sony’s Xperia ion is a big disappointment and I would not recommend it. At this price, the HTC One X is a much better choice, and even the LG Optimus 4X HD makes a very compelling buy if you want to save a little. The ion just seems like a stop-gap offering till Sony can launch the Xperia T, the true successor to the Xperia S.

Google's Chrome: 7 Reasons for It and 7 Reasons Against It
It's an election year, and we're not just talking the Oval Office in the big white house on Pennsylvania Avenue. The battle of the browsers is getting fierce, and Google wants you to sign up for its campaign.
By J. R. Raphael, PCWorld Sep 3, 2008 5:30 am
The first beta of Chrome, Google's long-in-development Internet browser, became available Tuesday afternoon for Windows Vista and XP users, with Mac and Linux editions soon to follow. There's ample reason to be excited about the release, and just as much reason to be wary. Check out these screen shots, weigh the pros and cons, and then decide for yourself.
For further PCWorld.com coverage of Chrome, see assistant editor Nick Mediati's product review ("Google Chrome Web Browser") and contributing editor Harry McCracken's analysis of how Google's entry into the browser market affects the other major players ("Chrome vs. the World").
Seven Reasons Chrome Could Be Cool
1. It won't crash.
Perhaps Chrome's biggest draw is its multiprocess architecture, which, in a nutshell, protects you from having a bad Web page or application take your browser down. Every tab, window, and plug-in runs in its own environment--so one faulty site won't affect anything else that you have open. This approach also adds another layer of security by isolating each site and application within a limited environment.
2. It's really fast.
Again because of the multiprocess foundation, one slow site won't drag down the rest of your browsing. Instead, you can effortlessly click to another tab or window. With plug-ins, the arrangement works similarly: If you open a site that has a slow-loading Java ad, for example, the Java itself will be isolated and the rest of the page won't be affected. The program itself opens within seconds of when you click the icon, too--a distinct advantage over some slower-loading alternatives.
3. You barely notice it's there.
Calling the design of Chrome's interface streamlined is an understatement. The program barely looks like a program, and the vast majority of your screen space is devoted to the site you're visiting--with no buttons or logos hogging space. Chrome's designers say that they wanted people to forget they were even using a browser, and it comes pretty close to achieving that goal.
4. It makes searching simpler.
One of Chrome's signature features is its Omnibox, an integrated all-purpose bar at the top of the browser. You can type in a URL or a search term--or both--and Chrome takes you to the right place without asking any questions. Omnibox can learn what you like, too--a talent that goes beyond the obvious automatic completion function. Say that you want to use the PCWorld.com search function, for example. Once you've visited the site once, Chrome will remember that PCWorld.com has its own search box and will give you the option of using it right from Omnibox. The function thus automates keyword searches.
5. It gives you more control over tabs.
Chrome gives the idea of tabbed browsing new power. You can grab a tab and drag it out into its own individual window. Or you can drag and drop tabs into existing windows to combine them. Chrome also gives you the option of starting up in any tab configuration you want--whether a custom setup or the set of tabs you had open in your previous session. Other browsers require third-party add-ons to provide this capability.
6. It opens new doors on your home page.
Chrome comes with a default dynamic home page. As you use it, the program remembers the sites that you visit most often. The top nine of those appear in snapshots on your home page, along with your most commonly used search engines and bookmarks. There's no force-feeding here, though: You can override the dynamic home page with any home page you want, just as you can set the default search engine to any service you prefer.
7. It lets you stay incognito.
Like Internet Explorer 8's recent beta release, Chrome offers a private browsing option--one it calls Incognito. You can open a special type of new window and rest easy knowing nothing you do in it will be logged or saved on your computer. And unlike Internet Explorer's, Chrome's Incognito window is isolated from the rest of your browsing experience, so you can have your private window open alongside your regular windows, and each will operate independently.
Seven Chrome-Related Concerns
1. It's only in its first beta.
This is Chrome's first test release, so problems are bound to crop up over the coming months. If like most people you rely heavily on Web browsing, you run a risk by putting your online life into the hands of an unproven product. Visits to some plug-in-oriented sites such as logmein.com have generated errors ("This application has failed to start because xpcom.dll was not found..."). Do you want to deal with that kind of uncertainty daily?
2. You won't have any add-ons.
Add-ons are a huge draw for Firefox fans, and none of these are available in Chrome yet. Google does intend to create an API for such extensions, but for now you'll have to make do without your AdBlocks, Better Gmails, and BugMeNots--or you'll have to switch between browsers to use the add-ons you want when you want them.
3. You can't synchronize.
One big plus of Firefox is its ability to synchronize across multiple computers using Mozilla's Weave option. This arrangement allows you to keep your home browser, your laptop browser, and your work browser looking identical at all times--and once you get used to that level of synchronization, it's hard to give up. Chrome doesn't yet have that capability.

This arrangement allows you to keep your home browser, your laptop browser, and your work browser looking identical at all times--and once you get used to that level of synchronization, it's hard to give up. Chrome doesn't yet have that capability.
Standards get a little less standard as this new player enters the equation. It's based on WebKit, the same open-source system that drives Apple's Safari; but when you look at pages in Chrome compared to pages in Firefox or IE, you'll notice a difference in text formatting. And since most sites give coding priority to the market leader, you might be setting yourself up for disappointment with Chrome.
5. You're giving advertisers extra ammo.
Have you seen all the hype about Google's privacy practices and how much of your data it shares with advertisers? Imagine the potential ammo you're giving it by using this browser. Google will now have total control over your experience from the time you open Chrome to the time you shut down. In some sense, you might just as well invite DoubleClick to watch over your shoulder while you surf.
6. The dropdown bar is dropped.
The idea of the URL dropdown bar is dropped in Chrome. To compensate, the browser offers "intelligent" features in its Omnibox; but if you like being able to see your recent URLs at the click of a button, you'll miss the dropdown bar.
7. You lose some history power.
Chrome's History functions are less versatile than the powerhouse ones built by Firefox. Chrome offers only a simple screen showing your day-by-day history. The ability to sort everything by date, site, or most visited appear to have joined the distaff and spindle on the ash heap.
So there you have it: the good, the bad, and the ambiguous of Google's first foray into browsing. You've heard the hype; now, the decision is yours. Whose campaign will you be joining?
