Ben Hammersley has an OS X epiphany.

Geek Alert: I've got Gnome running on top of OS X/Aqua, and I'm using Gimp right now. Hands up all who love Open Source...

UPDATE: Hang on, if I can now run any Xwindows app, as well as command line stuff, and hence can use any Open Source Linux application as well as any native OS-X application, and use the Fink package manager to stay up to date...all for free...why the hell didn't I switch earlier?
