I use Bootcamp on all my Macs and regularly boot natively into Windows. Most of my PyParallel development is done in Windows 8.1 running on my iMac 5K retina. The only complaint I have about natively booting into Bootcamp/Windows is that the touchpad driver isn't anywhere near as nice on Windows as on OS X. The fact that VMware will happily boot a virtualized instance of the Bootcamp Windows partition (when I'm on OS X) is pretty damn fantastic too. In the past I've also been able to do the reverse: use VMware to boot OS X from within Windows.
