[quote name='Kaltic']I know this is off topic (somewhat), but are the digital version of the games any cheaper then their retail counterparts (if they have retail versions... for the 3000...)?[/QUOTE]
No, or at least not in most cases anyway. That's part of the reason why I ended up getting a 3000. Then there's the larger catalog of games on UMD, as it's highly unlikely that the entire PSP catalog will end up going on the PSN, at least in the foreseeable future. Further, the Go's battery is not easily replaced.
If the Go had launched at $150, it would be a good buy. IMO, $200 is really borderline, and $250 is completely not worth it.
