I don't have a PS2 + XBOX + NGAGE.
I will NEVER own any other them. Espcially the ngage and ps2. I have thought a little about getting an xbox (And I do mean a little, I spend too much money on my nintendo stuff to even get into xbox)

I will say XBOX does have AWESOME games out that I would love to get. It seems like that system gets all the games that would have usually been on gamecube, that I would have bought in a heartbeat.

Game that I would get for the xbox if I had one:
New conker title, new perfect dark title, mx superfly, crazy taxi 3, ninja gaiden, and I know there is like 15-20 more title I would buy in a second but can't think of them at the moment.
