Never going to buy a 7" no matter how cheap it gets. The screen resolution is not worth it.
The people are being hoodwinked into buying these so-called "tablets" of smaller sizes, where as, none of these should be called tablets, rather, they are just a bigger size phones with no traditional calling features. Amazon or no Amazon, you would be wasting your time, energy and $$ if you buy a tablet with anything less than 1024x768 resolution. Just don't.
