Well the PS3 is actually cheaper than the 360 once you add the wifi adapter ($100) and a year of live ($50?), and that's not even considering another year or two of xbox live, in which case you add another $50. The graphics are pretty much the same though the PS3 is slightly better... And tbh they both have great games, I don't really understand why everyone dwells on the "exclusives." Who gives a shit about exclusives, games are games, and they both have great games. PS3 (the older versions, not the new 40gb) has backward compatablity, the 360 does not. PS3 has a browser, though I would never really use it, just a pretty cool feature. The PS3 controllers don't require batteries, and they're alot lighter, but if I'm not mistaken they don't have vibration? So yeah the PS3 is really a better system and a better choice, but it's really just whatever the fuck you want. I don't understand why people argue so damn much about consoles, it's just games...
^I pretty much spit out everything that came to my mind, and for the record i have neither, I have a PS2 but have been researching these for a while and I really want to buy a PS3, but the only thing is all my friends have 360's :\ So I don't know what to do yet.
