On my quest to try out a Wii today, I saw a Dual Shock 3 being sold in the local toy store. Seeing that there's no Wii around to keep me busy, I took the plunge and bought the Dual Shock 3.
I came home and tried it on the first game that I know supports it: Uncharted. First impressions: Wow, this is definitely something Sony did right on the PS3.
I'll test it further later and post more impressions here.
