well I bought a PSP Go and I love it.
through october the psp offerings on psn have gone up by atleast 130 games. Plus I don't care if you claim the design looks like cartman. After plaing with it for 50 hours then trying to use my friend's psp 3000 I realize just how good it feels. My DS Lite feels like an actual brick now. And you wouldn't believe the convinience of being able to switch from game to game with such ease. Plus the large memory lets me use it like an ipod. Plus I am able to play monster hunter with a ps3 controller(watching the psp go while not holding it is less of an inconvinience than you might think) with the new bluetooth.
I am not too lazy to go and change dics, It just feels a ton better. Like the difference between an ipod and a cd player. On a cd player you are more inclined to listen to a cd the whole way through but on an ipod you switch between individual songs depending on your mood. That is what it feels like.
I immediately bought Monster hunter freedom unite and jeanne d'arc. When I am done with those I might get half minute hero or Dissidia and after that who knows. GTA chinatown wars or any of the psn originals are goos choices. And every week is like a month's worth of releases on PSN with like 5 to ten games coming out. I just don't understand all the hate it is getting.
