I've been playing Age of Empires 2 online for quite a long time until Age of Mythology came out, but currently, i simply don't have the time to play pc games, there are other things which take priority right now (school, band, friends...)
Doesn't really appeal to me, with the exception of like Halo, every game i want comes out for at least one of the other two systems, or the computer, so buying an x box would be a total waste.
