Am I the only one who uses the numeric keypad in "num lock off" mode? I got into the habit with my Northgate Evolution, in which the arrow keys in the inverted-T configuration and the home/end/pageup/pagedown clusters are in between the arrow key halves, so basically impossible to use without looking down. The arrow keys feel more natural when they're centered in the middle of the board, instead of being shoved all the way down at the edge, and I have easy access to pageup and pagedown. Plus, if I really need to type out some numbers, I still have a number pad just a toggle switch away.
The Microsoft Natural Keyboard Elite that I used for years had a pretty screwed up arrow key and key cluster, and I survived just fine. I think these keys are the first ones to get rearranged, so it's kind of surprising they're chosen instead of the numeric keypad (which is less likely to get rearranged) to stay with the board.
The only problem I've had is pushing alt-home instead of alt-left to go back in my browser, thus reopening my home pages. I don't think a lot of people use that key combination anyway.
So I ask, why are we getting rid of the numeric keypad and leaving the quaint arrow keys and home/end/pageup/pagedown cluster, when we can remove the latter and have a keyboard with the width of a tenkeyless (ok, it's one key wider) and still have a numeric keypad, thus getting the best of both worlds? Has any keyboard manufacturer tried this and had it fail miserably?
