I don't want to use bloody Linux
After being an ex Linux Admin, tried pretty much every distro ... I settled back on Windows as my OS of choice. I don't want to use linux with all it fragmentation between distros, libraries and all sorts of other crap that tend to break, I can't be bothered with it anymore.
Windows 8 works perfectly fine, the chap that reckons he was having problems is either lying or shouldn't be anywhere near a computer. Every game that has worked with a version of Windows NT has quite happily worked with Windows 8 so far, I even install Alien vs Predator 2, Unreal Tournament and even the original Unreal.
Games that need Admin rights are trying to save to the Program Files directory than in My Documents as they should.
Lets see how much money Valve can throw at beating not on Windows, but Xbox and PS3 for their Steambox to become reality.
