1. 2 Screens, small and low resolution. I don't care about innovative but I'd accept it if the screens weren't so crap.
2. Size, sorry too big nuff said. Due to number 1 of course.
3. Low audio quality, it is 2005 I expect CD quality music and effects.
4. No FMV, See above
5. Expensive games (well in Aus at least) seems to be dead on arrival here, will probably sell consoles but no games.
6. Games, not enough of them and most 1st party games will be ports
7. Grahpics, Nintendo has always dumbed down the handheld market. The DS was meant to be 2D before the PSP came out. Nintendo has never made a handheld which they lose money on selling, on the contrary they make a profit off each handheld therefore the hardware is always cheap and crappy. Sony are losing money on each PSP.
