Excellent points. I'm very happy that I didn't sell my PSP 3000 personally- and I'm very close to selling my Go.
I was in love with the thing when I bought it and I still am, but the pricing structure is just flat broken. I had always thought that the game downloads would be at a discount over UMD's but they're exactly the same. If that's the case, then I'd rather just buy the disc's and take advantage of all the holiday sales.
Ain't no buy one get one half off on the PSN.
