Also, I outright disagree with some of their observations about ease of use. They say that Windows is actually pretty good at hand-holding when you "troubleshoot" something. Me? I've never once had any success using the "troubleshoot" tools to fix something. I've never once had a problem I couldn't solve by a quick search of Ubuntu's forums/documentation and editing the config files myself.
And I almost laughed when they said Ubuntu should use ideas from Windows UAC... All in all, I really think this article fails to realize the difference between Ubuntu and Windows. I don't think Ubuntu is trying to BE Windows. If anything, they're trying to reaplce it (and I don't even think that's their goal). There's no point in competing with Microsoft if you have the same vision as them. Ubuntu has it's own goal, so does Mac.
