I would buy one if it wasn't so much more expensive. I have someone who'd be willing to pay almost full price for my PSP (2000), and I could put that towards a PSP GO, but I don't want to spend another hundred dollars for a system I already own.
Like Rainbird said, portability is the big thing with this; it would be great to have a smaller handheld and have all of my games stored on the PSP itself. Plus without the UMD, there's a possibility that the battery life is longer. We don't know that for sure yet, though.
I'd also like to add that I was never a huge supporter of blu-ray on the PS3; it's nice to have and I do enjoy it, but I don't think that it was necessarily needed. Changing discs every once in a while won't kill me, and if I'm too lazy to get up and change a disc in the first place, then I probably have other problems.
