ah, thanks.
i couldn't afford 2 PSPs, and it's really a setback if i had to switch OSes constantly.
no keyboard for the psp, i already feared that. i tried the in-psp-browser today, and beside the fact that it's extremely unhandy due to the small resolution (some smartphones reduce the website size by 50 or more per cent, why doesn't the psp do that?), i didn't like the mobile phone style input much. maybe just because i'm not accustomed to it.

and for the "official games" - is it worth getting the psp?
