I just bought a Nexus 7 after a long break from Android. I had an awful experience with an LG phone running gingerbread.
I'd just about given up on Android, but I decided to give the Nexus 7 a try, after all what did I have to lose for only $199-249?
I'm happy to tell you this device is really exceptional. It singlehandedly changed my whole opinion of Android. It is the best 7" tablet on the market hands down. It absolutely stomps all the other small Android tablets including the Kindles and nook. I'd say it's arguably one of the best tablets you can get of any size actually.
Android has come a long way since my last gingerbread device. Jelly bean is far more polished and slick and getting a Nexus device means you get pure, unadulterated Android free of skins and junk that slow the device down and you'll be free to get OS updates as they come out.
It's an easy decision, It outclasses all the other devices in its class, only the iPad mini comes close and the Nexus offers higher resolution, twice the RAM, twice the memory and a faster processor for $100 less. Game over.
Best purchase I have made all year. I feel like I am stealing paying only $249 for this thing. It would still be a good deal for $349. At $249 its an incredible value.
