I have an associate who recently switched from a Linux host to a Windows host running Linux VMs. He spends almost all of his time in his Linux VMs doing dev work, but finds it very convenient to have the Windows host when he wants to play a game, run Photoshop, or do one of a handful other things that don't have good equivalents on Linux.

It's almost tempting to switch to a set up like that but I don't have the heart for it.
