If it was complaints about Linux that you were looking for, why didn't you say so? Let's see now: No standardizations, hence everyone has a different version. If you need a tool you'd have to hunt around for hours to get the one that you need that is made for your OS. Or you need to be a g33k and compile it yourself.
Mankind has been evolving towards making life easier for himself. Yes, I'm too darn lazy to compile something each time I want to try a new software on my computer. And Yes, I love the games on Windows. I don't want to install Wine and hunt around days for the right settings to play a game that works right out of the box on Windows. (Note - not all games work right out of the box anywhere, but that isn't always the Operating System's fault)
@achemist4u: It's all about the opinion of the individual, but a lot of people have had bugs with Vista, and a lot of people like Linux, which I have never heard a complaint about. You'll probably never see this, and I respect your opinion.
My computer has Vista and it has crashed once in the year and a half I own it. I don't see why everyone is so down on Vista. If you can't make a better os, don't criticize
