Yup. I did that just today. It always takes me a moment to realize it and then I have to figure out what got deleted.
NumLock isn't a problem. I mostly use a laptop with an external keyboard. Both have separate keypads. The other laptop doesn't have a numlock key or the keypad on the letters. It also doesn't have a removable media drive, enough USB's, or an ethernet port. But hey, it's thin and supposedly light. And wider and deeper than the one with the keypad.
Everyone needs at least one Mac in their life.
(The above is an attempt at a self deprecating joke by a long time Mac user who simply recognizes that some of the recent design choices made by Apple can be frustrating to users. It is not an attempt to derail into a Mac v. Windows v. Other debate.)
