I have one machine in Linux and another in Windows. I've also made bootable persistent thumb drives to save myself any accidents creating a dual boot. That way I can run Linux for daily stuff, and Windows when I'm too incompetent to figure out a workaround for a game or whatever.

Windows needs to be rebooted all the time anyway, so it's not really that big of a deal to boot into something else now and then. Plus it gives you a little change of pace.
