Not trying to single anyone out, but I find it funny that many people that complain about DRM issues have no issues using Windows.
Personally I like what Valve has been doing to bring some games to Linux, I would be stuck with playing games exclusively on playstation or using WINE on my older games with varying results. Not saying there is not some downsides to DRM or the steam purchasing model, I just like being able to some of these commercial games on the OS I like using. I have more of an issue giving Microsoft money for crap products then dealing with some intrusive copy protection on commercial software.
