Brad Choate is considered a Movable Type guru. (That's the weblogging tool that tons of sites use, including Operation Gadget.) He published a list of software that he has installed on his Macintosh since he switched to a 15-inch Powerbook G4 back in October.
I'm always interested in the programs that people run on their Powerbooks. Some of the coolest applications get developed for OS X and I never seem to get to run them. Brad has a good list of programs here that will be of interest to people in the software development and system administration communities, and a good mix of commercial and free software.
