Windows to Linux

I'm thinking about switching to Linux. Specifically Ubuntu or Fedora. Anyone want to tell me why or why I shouldn't? Currently using Vista Home and I like it but I just want to see what else is out there. Plus if its more secure, thats always a plus.

Tried ubuntu? To install a program, it's really just a matter of downloading a file, clicking on it and choosing install. Alternatively; going to the installation program, selecting it, and choosing install, without having to hunt for it on the interweb.
Cute inequality typo, though. ;)
