I've had my MacBook Pro for a couple of months now and I've officially switched over to a MBP at work as well. All this time I have been working without a delete key. That thing labeled 'delete' on my keyboard is really what I have known in the past as a 'backspace' key. Naturally, I assumed ⌘+delete would give me back my true delete functionality, but that didn't do it. It turns the magic key combination is Fn+delete. My productivity should go up now! Yay!
