It is overall very well designed and very well finished. The screen is great, it will be hard to beat. The front touch screen is also very good, everything responds with great responsiveness, RAS.
By cons, some details really unsatisfactory, such as plastic that closes the port game. This disorder makes the rest of the machine, besides it is not easy to open, certainly I know it drives us to have dematerialized games, but still.
A scandal, the console comes with no memory, forcing to buy memory cards (of new and expensive format) !! Sony has clearly blown a lead on this occasion.
Another major concern, at least for me, the rear touch screen, which will remain a gadget for most games. With my big hands and big fingers, if touch pad is enabled in games, impossible not pressed it by mistake. So I off, the problem is that in the game I play, it serves to adjust the various zoom levels. GRRRR ...
For the so-called lack of game you PSP games, enough to provide a nice repository pending more VIta games.
Finally, 4 stars for this too shunned console and underestimated.
