1. Sony counters with shorter battery life because playing games with a big screen and lots of performance chews up power.
2. Sony sticks the screen right out front in order to be scratched by keys etc, whilst Nintendo has a clamshell design.
3. Sony counters by allowing people to play games effectively which have never sold substantial numbers in the first place on handhelds.
4. Sony puts in a big screen, big battery, big case, complicated internal electronics because to compete they need to really have a price which is cheaper than the 3DS? Personally I think the PSP2 will be $299-399 and Sony will sell it in part as a small tablet PC.
Tease.
