Ok, that's kinda funny! Here's your +1, my good AC!
I'm with the GP: I only play a few games, but none of them will work well in Linux. I've even grown sick of trying to get WoW to run in wine (granted, I tried on my old laptop with a 945GM chipset, which was notorious for linux incompatibility).
I'd like to learn to set up a complete linux shop, but our engineers need AutoCAD software that I doubt would work in linux. Even if it did, we don't have the know-how in the company to set up all our customizations for it in anything but Windows.
I'm excited for Windows 7. I hope our company migrates to it soon. XP is started to feel really dated.
