Still not sure whats crap about the go? Its screen is slightly smaller by a about 1CM but its brighter doesnt have the ghosting of the 3000, its smaller, lighter has improved controls and is far more portable when closed up than the old PSP. It has built in BT so you can use BT headsets, sync to a tethered phone for online stuff, and linked to a PS3 far easier.
I would think loadng 10-20 games on the UMD drive would be far easier for someone to play games on, no need to carry a bunch games round with you, no danger of loosing or damaging the UMD or even the boxes, just select which game and play. If you havent got a PSP then a PSP go makes a good purchase, if you have a PSP with loads of games and accessories not quite so good as the accessories wont work and the UMD trade in is yet unkown. The price is still the stumbling block, but it looks like £200 will be the selling price.
Still think some of the "hate" on the Go is nasty pirates not liking the idea that they cant seem to be able to crack them so easy, a lot of the homebrew apps sounds like they could come to the PSP app store so those who only use it for the apps cracking gives you (never to play illegal games on) will still have a way to use them.
