Is their a way that I can GLOBALLY map my keyboard shortcuts on my Macbook pro to match windows shortcuts? (Cut, Copy, Paste, Beginning of Line, End of Line, etc...) I go through spells where I am switching between the two and have been doing so for at least 3 years.
In OSX 10.7 Lion (probably the same under 10.6):
System Preferences -> Keyboard -> Keyboard tab -> Modifier Keys
Remap command to ctrl, ctrl to command
That should get you close, although if you ever let anyone else use it, they may get a bit confused if they're expecting the defaults.
