To make it short, I HIGHLY recommend it. It's so superior to windows, it's not even funny.
Here are some of he advantages I've seen so far:
It's FREE, all its applications are also free, and it can run most windows apps (in case you don't like the free ones, or you need something that's not supported).
It's so much faster than windows, you're gonna think somebody switched your computer.
There's almost no viruses for it, so you can kiss your antivirus goodbye.
It comes preloaded with Firefox, plus a bunch of apps including a word processor, spreadsheet, presentation software (like powerpoint), picture editor, GIMP (image editor), and a lot more.
But the most important part:
IT NEVER CRASHES!!!
And you have free community support at ubuntu.com, which is, by far, the most active forum I've ever seen.
Try it. You'll love it.
