My other gripe is that they don't have the same trophy system across both platforms. It seems like a missed opportunity.
That's great if people need all that stuff. I use iPods, iPhone, iPad for music, internet, etc. I think the PSP's advantage is a back catalog of old, classic console games, and some new ones that are good too.
There are some fun games on Apple stuff, but I don't think of the iPod Touch or iPHone as gaming machines. Maybe some people don't have other devices for those things, though and it's great for them, but for me I just need it to play games over internet.
