Those are good but Genesis 3 was an abomination.

My favourite is indeed the PSP Go. It is just so small and cute, it fits right into your pocket and it is just about the greatest retro handheld ever made. I'm actually glad it doesn't have a UMD drive, because otherwise it would be a whole lot clunkier.

Losing access to UMD games is not a minus in my book. CFW is the way to go to get all games ever released on the system, even those with no digital release. Plus you can play NES, SNES, Gameboy and PS1 games and whatnot. Yes, it's probably not perfectly legal and stuff, but I don't care. The PSP Go with CFW is one of the greatest handhelds of all time.

Just had to get that out as the PSP Go gets so little love in here. =P
