PSP still seems to be selling quite well, 450,000 last week (19th). I may end up buying a PSPgo, I've never had a regular PSP so I don't care about umds. Portability and battery life is more of a factor for me. I have a PS3 and the remote play sounds interesting, and i've downloaded lots of games from PSN for the PS3, so I'm used to the 'no physical media'. The price seems high, but I've seen them at Fry's for $199, and Dell had them for $210 shipped. My point is: people who already have a PSP might not like the upgrade path of the PSPGO, they can't use their old games/accessories, but a new comer like myself might prefer the lighter GO.
