As a programmer who switched to a mac (without a delete key), I also used to think the delete was crucial. I'm curious, what are you using the delete key for? I've only ever used it as a backspace-but-reverse when typing, and to delete things like files in GUIs. The workarounds for these issues are trivial (change your cursor's position for the typing issue, and GUIs respond to backspace with a modifier key), so I'm wondering what other (not-as-easily-emulatable) functionality the delete key gives
