I have Vista on my laptop, but only because it came pre-installed. Also, I wanted to experience it for myself, as others were saying it was poor compared to XP. I have found that on a standard spec machine, such as my lappy, it does run quite slowly, and I am often sitting there waiting for commands to execute. For example, it can take up to 60 seconds for Firefox to launch from cold, and the Send To command takes forever to get the actual destinations menu to pop up. I haven't had the crashes that some have reported, and also haven't had any real compatibility issues, so I wouldn't say Vista is totally bad, but I did install XP on my new machine.
