Yea I dunno...KDE isn't too bad. I used to use Kubuntu but I fell in love with Win 7.
Yeah, my main machine is a gaming machine and thus it's usage of Windows 7, and I don't care what any linux gamer says, you can't really use linux as a primary gaming OS if you play games almost exclusively on the machine. I suppose you could but the success rate will be lower. Being able just drop the disk in or double click the icon in steam without having to try various versions of wine, cedega, or tweak countless game specific settings is not just a perk, but a requirement for a gaming machine.
If you have to fight to get a game running on your operating system, the machine it's installed on ceases to be a gaming machine... and with the number of games I play it's just not an option. All you linux gamers, don't hate... just understand that for a gaming box, I want maximum compatibility and ease of use. I want less pc and more console when it comes to getting my games to work, but more pc and less console when I'm playing them.
All that being said, most of the games I'm playing nowadays appear to have native linux clients... quake live, quake 3, minecraft, unreal tournament 2004, etc. It's sad to see most of the big firms have completely abandoned linux, epic and id included if I understood what id said about rage correctly (no linux support). Hopefully that isn't the case and I'm misinformed... valve supposedly is gonna make linux gaming easier with steam however. If I start seeing a large amount of games available on steam for linux I might just make the hop over to linux and start playing. :O
Oh, and another thought, until recently my home server ran linux. Now it runs windows vista ultimate because everything just works on that too. Media streaming to my 360, file sharing with windows boxes (in case you don't know, samba is slower than windows for windows file sharing by a considerable amount, probably 10-20%). I am probably going to give it a try again so that I'm not just saying die... now that I've got that machine mostly optimized for the service it provides on a hardware level. I need to get it re-oc'd and get the fans running quieter because right now it's running infernally loud.
