Cheers Grey Ninja for starting this back up.

"My next projects are finding some decent Radeon drivers, and figuring out how to start installing some more well-featured programs, such as XMMS, MPlayer, a Linux Bittorrent Client, a better File Manager (I hate Konqueror), or some Linux equivalent of Trillian."
There is a distribution of Bittorrent for Linux, I think it is at the official site - it is console based, although i'm sure you could find some nice frontends if you really wanted them. Trillian (if it is what I think it is!) there are several solutions namely GAIM and Kopete. If you running KDE, most likely want to go with Kopete as it is a KDE app. Konqueror, I believe you may be able to use a split view like Windows Explorer if that is what you want, it is quite customisable so play around with it. There is also XWinCommander which is a 95 Explorer clone, only problem being it's rather ugly (not QT or GTK, Motif I think). Personally I use GNOME and Nautilus, which are pretty good and getting better all the time, but MIME support is pretty dodgy at the moment.
If you're having trouble with MPlayer, try Xine, it's really good and I believe has full support for DVDs now, including menus, so you don't have to have Ogle as well. Also with the XMMS problem, you could always see if it happens with JuK (KDE jukebox) or with Rhythmbox (one of my favorite Linux apps!). Third mouse button? Don't have a clue. Poke around KDE Control Center for starters, then I guess use trusty Google.
Some other decent IDEs BTW are Eclipse and Anjuta, I just use Emacs myself

. Personally I think programming is much nicer on Linux/UNIX than Windows, everything seems a little clearer, and better designed.
Resist the urge to delete the partition. TRUST ME, once you know it it is worth it and so much easier to get work done, especially once you've got the command line pretty much mastered. Also, now you've got 3D acceleration going - why not break out the old America's Army, or Enemy Territory

PaleZero: You can run Maya and Photoshop on Linux. Maya is native, but Photoshop needs Codeweavers' Crossover plug-in. Or better yet, you could use The GIMP, the 1.3 series of it is amazing, definately up there with Photoshop.
