As you may have read about lots of places (like this: UMPC will destroy PSP) UMPC is thought to be an obvious Psp killer. I believe neither Microsoft or Intel or manufacturers think that. Yes, you can play Much more better games and there is much much more games on UMPC, and PSP’s other “major” futures like multimedia, browsing etc. are much better on UMPC, but that is not the point. They are different catagories. We all have computers and computers have the best games comparing to the consoles (not including Halo 2 :D) but faster and better computers didn’t stop PS1 and PS2 selling. PS2 can play movies, browse the internet too but they are not its major selling points. Sure UMPC will make people say “why i’m torturing myself with this small-displayed, hardly multimedia and browsing capable thing with movies only play on it and have no hard disk drive instead of a nice UMPC?” and a lot of people will buy UMPC instead of PSP, but again people bought PS2 (for lots of reasons) and UMPC will not be able to “kill” PSP, but it sure will injure it badly. (and although PSP can’t fit a pocket, it is much more smaller)
And same thing of course applies to iPod too.
