I personally own an X-box, but I like the 2 systems close to equally. The huge internal memory of the X-box is awesome, but having to buy the DVD playback kit is just a little hassle (although not really expensive).
The argument last year was the number of games available, and the PS2 was far ahead, but now theres a huge selection of x-box games.
Both systems are starting to go with the interactive play. This is really cool, as I've killed many friends in Halo that live no where near me. And by the way Kevin, if you buy an x-box, you are pretty much required to buy Halo, as it is the best game ever made

its one of the oldest X-box games and theres still such a high demand for it, its still $50 in stores!
If ya wanna come by my place sometime and try out the x-box, feel free. I've got a few racing games, and a few "shoot-em-up" games too.
see ya,
