ctrl-arrow (which breaks with Lion's Spaces default keys), or shift Home/End in Terminal.

It's not that Macs are crappy, they just have different key bindings. I regularly work with Macs, Windows, and Linux for development and I've just learned to use the different key mappings.

I don't think I'm quite as proficient in any one system because of that, though. For example, I have avoided learning the Emacs key bindings for use in Mac/Terminal. (I don't want to try to remember TWO bindings for Mac, plus I learned vim first so usually avoid Emacs.)
