PC World: "After recently writing about the 'joys' of upgrading from XP to Windows 7, I was mildly surprised to hear from Vista users who wanted to know if they should upgrade to Windows 7. The answer is: "Probably." Here are the issues you need to consider as I see them.
First, let's get this out of the way: while I'm not saying whether Vista is good or bad, Vista was a less good product for Microsoft. That's not my opinion, as someone who's known for preferring Linux; it's also the opinion of Charles Songhurst, Microsoft's general manager of corporate strategy. So I don't want to hear any whining from Microsoft fan boys about how misunderstand Vista was and how, by Vista SP2, it was actually a good operating system. It wasn't, it still isn't, and Microsoft knows that as well as I do."
