lol i checked this out its pretty funny i looked at the details in game so funny
webcam - you could buy one speratley for the psp ages ago
sim card/ phone - erm skype ? but had to require wi-fi so slight improvement
Touch screen - really nobody touches a screen to play games , espically with buttons and two angalog sticks (unless you have an apple something e.g ipad) but two arent excatley required .... one i thought was fine.
seemed to me that you could do all the things on a psp vita you could do on the psp slim and lite already !!!! just had minor improvements and then the battery power will be possibly be slighlty longer than the slim and lites one but when actually using it, it wont last as long i.e to connect to internet, play games, call people so not much different , basically just get a old psp with 1 analogue stick it does the job already .....
