Well, hell has finally frozen over as I've made the switch (at least for work) to Apple. Specifically, 17" Powerbook G4 running OSX 10.4 (Tiger).
I like what I see so far, now its just a matter of learning everything all over again.
My biggest gripe to date is not so much with Apple, but with the fact that eclipse is so much slower under OSX than Windows or Linux. Its kinda ironic that I make the switch from linux to OSX for development work right when eclipse is finally performing acceptably on GTK - exactly the same scenario when I made the switch from Windows to Linux. Lets hope that the performance improvements for OSX don't take as long as they did for GTK!
