Well given your preference toward anything Linux I'm not really surprised. I will say that Nichols article did hold my attention from start to finish, something Extremetech has a hard time doing for me regardless of the article it posts. In fact had an easier time reading the comments about the article than Extremetech's article itself. The problem is that unless Linux can some way play HD-DVD's let alone legally (in the US anyway) regular DVD's or Games, Microsoft is (sadly) still the only game in town. Now that might not matter to some people but lets face it we are posting on a gaming site, so I'm guessing that games matter to some people here like me.
Given that I don't currently run a Linux OS on my system I have to take Nichols word that Linux Audio programs have some catching up to do compaired to Windows. Well IMHO Linux could also trim down the number of Linux distros out there, make the installation and file system more user friendly. It could also legally allow DVD playback and have gaming support (and not just for servers) in the US, wait that would require DRM support... *Sigh*. I've only written three sentences and I can already see why Linux is not a common place in desktops and Laptops across the US. I want Linux to succeed, to that end people like us need to push Linux and the people behind Linux to make it the OS that people really want. Otherwise Linux will continue to be the niche OS that it is.
Sorry if I'm offending anyone but that is just the way I see it. Linux needs work, a lot of work, but it also needs our support.
