It's been a few days working with Fedora at home, and so far it's going well.
Unfortunately I'm not able to completely dispose of Windows since I still need to use Quicken and there isn't anything comparable available for Linux yet (that I've found anyway). Fortunately, thanks to the magic of virtual machine (VM) technology, that was one problem I was able to get around relatively easily. Downloaded and installed VirtualBox, followed the instructions to create a new virtual machine and booted it up with my Windows CD. Took a couple of days to get Windows and all the updates installed, but now I have a working Windows VM running in my Fedora install. This VM thing is pretty cool. A little slower than an actual computer, but not so much that it's unusable. Now I just need to figure out how to get the VM to grab USB devices so I can use my PDA and scanner to get things into Quicken.
