Text editing on the keyboard also drove me crazy for a while. You do get used to it. My lingering complaints: the insane placement of Cmd for Cut/Copy/Paste (talk about a Vulcan Nerve Pinch!) and the mental shift required when switching back and forth between the GUI and the shell. (Mainly that's remembering to switch to/from Control/Cmd).
I love using Command-C to cut and paste throughout the OS including the terminal, rather than having to switch to Control-Shift-C for certain things as you do under Gnome, where forgetting means canceling something.
