Nice ! Hope it will keep Sony honest (Read: roll out compat. library + Gaikai -- at least local version -- fast). Will probably hurt PSP in Asia more than Vita though.
Those back speakers -- if they are speakers -- will be covered up during use.
These units will be pre-loaded with pirated games and movies in the stores.
A visiting friend got a 7" ICS Android tablet from China for US$80 or less. Loaded with emulators and Android games/apps too. Battery lasts a grand total of 2 hours, and screen is blurry/interlaced. I was highly impressed nonetheless.
Next day, I crashed it accidentally by copying 60 photos to the existing \DCIM\100ANDRO directory. Wouldn't boot after that. Took me a good 5 minutes to figure out what's going on.
One thing I never understood about these knockoffs - when they're THAT similar in build, isn't there SOME kind of infringement they can sue their pants off for? I mean COME ON, even the raised edges that go around the dual analog sticks, face buttons and d-pad are identical to the Vita.
