I use a few different systems daily, but normally the majority of my time would be spent between my a1200, my amithlon/os3.9 box, and aros. I say normally as my house is in a bit of disarray at the moment, so things arent "normal" right now. My Windows usage is normally PaintShopPro (so much better than photoshop for hand pixelling), 3dsmax, and watching videos when Im in my bedroom (which I also do on amithlon/os3.9 and aros sometimes, but I like to watch them on the t.v. in my room, and Windows is the only system of the 3 that allows me to use the t.v. as a secondary(concurrent/seperate) display). Unfortunately my network relies on my windows box as well, so it's pretty essential for me despite not getting as heavily used as the other systems.
