Of course, when an OS crashes like no tomorrow, it's another problem entirely. (That's what happened with openSUSE and my old desktop)
Nuking Windows on the laptop means that OS X gets a chance to be used all the time, and in the week, it's a pretty awesome experience.
For some reason, the dragon wallpaper I've got on my Mac right now also clued me into color calibration issues.
I've gotten pretty used to how things work in the OS X environment at this point, and I've also installed the Windows 8 Release Preview on Parallels (bought via cheap bundle)... it works better than expected.
When it comes to playing games, would you go Parallels or Boot Camp? I've noticed negligible performance degradation, if any, at least in 2D graphics performance. You know it's a problem when Safari on OS X is relatively slower than IE10 on virtualization
