Yay! After less then a day of futzing around, my primary production desktop has upgraded from Linux Mint 15 / Windows 7 Pro to Linux Mint 17 / Windows 8.1 Enterprise Edition.
Massive improvements in Mint, much better control panel performance and too much good to even list :)
And, for all the grief that people give windows 8? I love it. Huge performance boost over Windows 7 - faster boots, faster application loading times - hell, I think the upgrade was worth it if the only thing they updated is the damn File Manager. The File Manager included with Windows 7 would drive me to rage, lots of the rage inducing elements have been polished in 8 - and I like that :)
