You have to compare the 360 to the PC before you compare it to the ps3 IMO
A year ago I would have said that that's an easy decision, but PS3 has really stepped up its game recently. If you have an HDTV, I'd say stick with the PS3. It probably has longer legs anyway. I doubt that developers have pushed the PS3 as far as it can go, while the 360 is gonna hit a wall soon in terms of technology. And the PS3 has kinda embraced stranger side of gaming, which I like.
PS3 = Blu-ray/entertainment + increasing tech discovery of raw power + 3d gaming... yes you read right it's coming. http://gear.ign.com/articles/104/1047596p1.html Wii= Fun factor, let's face it, wii looks crappy but group games are fun.PC= Hardcore, best of the best graphics and always developing hardware.360= Red ring of death + fee's for everything (online, patches, ect)1 of these does not fit...
