linux is a business OS period. It is unix based and requires a lot of knowledge. The average person cannot handle it’s quirk’s.
Something is always wrong. Especially if you have current hardware. I doubt very much Ubuntu or any linux distro will support the ATI 5870 or 5890. You won’t even get a screen. The display code will blow up, and personally I don’t have the hours to spend trying to get current hardware working with linux.
Windows 7, while being more expensive, is LIGHTYEARS ahead of any linux distro for the HOME user.
Keep linux where it belongs, in the business segment. It will never achieve home desktop success. never.
sorry folks, that’s just the way it is.
