If you're going with PSP's I'd go with the 3000 ....
- Bigger screen
- Cheaper
- Uses cheaper memory cards (the GO can only use Micro cards)
- More comfortable to hold
Unless you're planning to really use the PSP as your MP3 player/iPod replacement ... then get the GO, but be ready to put down an additional $70 for the extra 16GB memory stick.
You're likely to look like a dork either way playing a handheld in public (lol), though the PSP Go is a bit more discreet in that regard.
