although I find it cool to watch movies and anime on my PSP... I really don't see the point in downloading ~100 mb just to watch it on that tiny screen... granted I did it a few times, but after about twice the coolness factor starts to wear thin. And for portability, I'm more likely just to use PSP Video Express on something I already have if I want to show it off, so I don't really think its worth doing.
Breakdown:
Pros- Cool!, portable anime, uber otaku factor
Cons- small screen, bad outdoor lighting/glare, not near as cool by number 3 as it was with number 1, and you might as well still download the full size divx/xvid version anyway.
my vote goes for no.
