The PSP's browser (at least my 2000 browser, haven't tried the Go's) is, to put it simply, a piece of shit. I could only read a newspaper and search in Google, I couldn't even check a FAQ in GameFAQs (granted, the WiFi there wasn't very good, but still). I have no idea how the iTouch's browser is, but if you're not getting the Go to play games but to use it mainly as an online device, forget it, I'm sure the iTouch is better
