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.

The Ubuntu installer can make its own new partition in the largest available free space, so there isn't even any need to fuck around with partitioning it yourself.
