OI just installed psx (playstation)emulator on my vibrant, it flies with no lag. The phone is awesome for gaming, was playing metal gear solid and mortal combat 4. I am enjoying the vibrant, I rooted it and now just waiting on custom roms. If anyone is looking for a new device, I recommended the galaxy s. I still enjoy using my n900 but the vibrant is my primary.
Seriously .. captivate ROCKS! dunno why they gave us that shitty GSM version .. it's damn ugly ! Vibrant < Facsinate < GSM < Epic4G < CAPTIVATE !
I wanted one of these and am still lusting after the Nexus S (the "vanilla" model selling through Best Buy). Unfortunately the Nexus S is plagued by the same GPS issues as the other models. That was the dealbreaker for me -- I "need" working GPS on my phone because I get lost very easily. The screens are gorgeous, two of my co-workers have these phones and they draw the eye from across the cubicles (in a good way).
