The last Fedore I installed was 8, back when I was working at the university. So far, it's been interesting. I'm finding that KDE is very different than Gnome. But it does look nice. Package installation has been smooth so far - which is good because there's a lot of work to do. I've got PostgreSQL, PHP, Pear, PostGIS and Firefox installed so far. Still a long ways to go.
We've talked a lot about how Linux includes a lot of stuff out of the box, which Windows doesn't have. I'm finding that's just not the case anymore. If you install Linux from a live CD, it's pretty sparse. Takes a good afternoon with the package program just to get things moving. However, the fact that you can get pretty much anything, including a whole new GUI, from the package program is pretty useful. With Windows, you have to sit there with your CDs and product keys, and obviously this way is much simpler.
