If the PSP-go is off the cover slides over the screen to protect it from scratches. I still play my UMD games on psp-3000 since Sony hasn't come up with a way to play them without the UMD on the psp-3000. Why should I buy a bigger hard drive for the PSP-GO when I am not going to get it anyway!
I bought Conduit and I like the game. Its a step in the right direction for Nintendo and I hope more games come out for the WII. As for Gran Slam Tennis I wasn't impressed with the controls and sent it back to Gamefly. Red Faction is a great game period.
