If you have large enough hands, it can even be held in one hand. It looks and feels like a gigantic Galaxy phone — all the buttons (capacitive + physical) are in their usual places and it even has a earpiece — though we didn’t prefer to use the phone functionality in this way. The downside is that it’s made entirely of white glossy plastic and just like most other small tablets, it won’t get you any second glances.
For the power user though, there are a lot of useful features. It has all the Galaxy features like multi-window, smart stay, pop-up play, S Voice, S Note and pre-loaded productivity apps like Polaris Office, Dropbox and Awesome Note HD. Like with the Note II, the stylus is pressure sensitive and works really well. The IR blaster + Peel remote app is a very welcome addition too.
Camera quality is good in daylight. We found no issues with the call quality and the battery should easily last you through two days with normal usage. At the end of the day, it boils down to this. If you need something with all the same features but in a more manageable size, get the Note II (roughly Rs 32k with a cashback scheme or Rs 27.5k with the buyback scheme). If you want all the same features but the 8-inch screen is too small for you, get the Note 800 (all the same features & a 10.1-inch screen for Rs 35k). If you need a small tablet but don’t want calling, get Apple’s iPad Mini.
And finally, we also quite like the Asus Fonepad which has some great features — a high-res 7-inch screen, metal unibody shell, 3G data + calling and is about half the price of the Note 510.
