your confussing a portable gaming device with a mobile phone.

300 for a new phone, yes.. on the cheap side.
300 for a portable gamming device.... that is powered by a mobile phone CPU/GPU... sorry mate.. doesn't sound like a good deal.

I can bet you tha the psvita is twice the better console with more games and cheaper! I don't know about the DS, but would rather a DS over this thing!

My old psp has emulators.. it's a mater of time before the vita is hacked.. also the vita has a good indie dev program if your keen lol.

If you buy one, don't open it, it'll be worth 10x in 10years when they only make 1 batch lol
