I'm using 9.02 atm and apart from a few flash issues that I had to play about with, I can't fault it on any machine.
If you have an old computer or laptop that is too slow for even Win 2k or XP, Ubuntu should run fast enough on it.
And, if anyone is half interested in it but scared of installing while they have windows you can do two things with the disc, you can play about with it before installing with the disc as like a live demo with the disc in and/or you can install on some free space you have on your HDD already without having to split the HDD yourself or un-install winblows. The install is simple and quick - I'd say give yourself about 10GB of free space though (the install is typically 699MB however)
I say to everyone who uses their computer every day, try it for a week and you aren't convince then go back - at least you tried. But for people who might use their computer only once or twice a week I wouldn't say its worth trying to learn a new tool you don't use much.
ubuntuforums.com will answer any question you want without becoming all tech-snob on you. The community there are more than happy to help anything as long as you do a search first as it'll of probably of already been answered anyway
