If anyone is looking for an inexpensive 7 inch tablet Amazon has one for $33 black friday special - also available at Bestbuy and Target for same price right now. With a bit of geek work it can be rooted and the Amazon operating system replaced with Android Cyanogenmod . I got one last year and works great for me in it's portable capacity . Link on how to root it is below . I am glad to help with that because care must be taken otherwise you can brick it.
