I don't want to use Windows ever again in my life (of course I'm talking about the current software made by the current software company, not the name Windows, this isn't a religious issue).

Also, rebooting takes ages. My Linux boot time might be measured in seconds, but I'm always in the middle of some kind of work and I use my running system to maintain continuity. It's a major pain in the arse to reboot, so I do it rarely.
