wow!...i generally hate these unknown brand names but the specs on that one look solid man!...price is obviously good...how's the build quality of that thing (or what can you expect?) ...gorilla glass or?...and i am assuming that it can be upgraded to 4.2...yes,no?
They are just rebranded Samsung/Toshiba tablets. Those factories in China have little trade laws on rebranding. You just need to watch the specs, the IPS screen, and a lot of youtube videos on reviews. Ainol has been around for awhile, so it's been around the block as a chinatab and has a nice following.
Check out the monthly manufacturing capacity of some of these factories for tablets. Pretty amazing. If they can do that, they can surely screen different brand names on tablets.
