Lest all the Mac people tilt this playing field, I'll weigh in and say I have a Windows laptop and desktop. I run a VM on each for Ubuntu when I can, and use Cygwin when I can't (I'm looking at you, Oracle, and shaming you for your USB device support under VirtualBox). I'd run Linux all the time if the driver support was there for my POS laptop, but it's not and I doubt it ever will be: I simply need the optimized Windows drivers for the display and battery. You can get A LOT of mileage out of Cygwin and the ilk - plenty for my needs. As a desktop/web developer, bash/vim/make/python, etc. are but a click away. I'd only get a Mac for iOS development, and even then I would hate my life under XCode.
