One of the factors that sparked my initial interest in OS X is the ability to compile and run the open source applications without which I can't work and play.

Thanks to two extraordinary projects--XDarwin and Fink--I can easily install and run my favorite free software such as gaim, Mutt, GnuCash, Window Maker, GKrellM and The GIMP on Ti.

I'll also be keeping a close eye on the DarwinPorts project.
