I bought a PS2 the day they came out years ago, its chipped which cause poop on some games, plus you gotta service the old ones cos of the bloody "non system disc error" that comes up, plus the dvd playback ain't that clever....
Got an Xbox about a month ago and it is SO much better, chipped to play multi region dvds so I don't need a seperate dvd player anymore
As for the point someone made about games on the PS2, yeah GTurismos good, but Need For Speed, Colon McCrae, Rallysport Challenge, Driver 3, they're SO much better on the xbox than PS2, trust me, I tried em on both
