What are your must-have apps?
GeneralMaximus: I'm guessing you mean apps that allow me to be productive. Not considering Twitter and IM clients, here's my list:* Terminal.app* The Python interpreter (I use Python for things like automating tasks, renaming and reorganizing files and even as a simple calculator)* TextMate* A nice little todo app called Anxiety (http://anxietyapp.com)* iCal* A web browser. I prefer Opera, but I really don't care as long as it's not IE6.* xPad (sweet and simple note taking program)And, of course, XCode and Interface Builder for writing Cocoa apps.There's only one app from Linux that I miss on OS X: AmaroK (or something equally powerful). I know I can get AmaroK on OS X, but there are way too many dependencies. I'm also not willing to sacrifice 400MB of disk space for a media player.
