Microsoft made a huge error with Vista in the compatibility department. I’m not talking about hardware compatibility but instead software compatibility. It was a huge problem for me. I ended up having to use VMWare to run Win2k virtual machines to run software programs that there are no replacements for.
Other than compatibility I’ve had very few problems with Vista. I can’t remember the last time the OS crashed.

The OS doesn't work, so I have to use a proprietary platform to imitate other versions of the OS a lot. Other than that, it's great.
It's like saying your wife is great, but due to compatibility issues you need to keep several mistresses around. Other than that, she's great.
Cheers!
Vista works flawlessly for me.
