While I really enjoy listening to MOD/XM, I haven't felt the urge to try my hand at it. Call it fetishism if you want, but I do like composing on a Game Boy that I can hold and carry around. And from a personal musical standpoint, I really enjoy the (in some cases severe) limitations imposed on me by "real" hardware. (I say "real" because I also enjoy software that imposes these limitations, like famitracker, etc.) The limitations force me to employ workarounds that often lead to results that can often be rather interesting.
Of course, I could impose those same limitations on myself with MOD/XM, but I'd totally cheat.
All that being said, I did recently download Milky Tracker...
I also think for newer people to the genre, a Game Boy or NES is easier to identify with.
