Many people, including myself, have little use for a numeric keypad. I'm neither an accountant nor a gamer.
Funny - I'm not an accountant and I can't think of any game I play that uses the numeric pad, but I find it useful, faster and more accurate for entering phone numbers, credit card numbers, login PINs... and even non-accountants have personal finances. Plus, you get full-size cursor keys, delete/home/end/page up/page down, a less cramped bottom row of the main keyboard (bigger space bar etc.). I'll reserve judgement until I've tried it but those cursor keys on the Tragic Keyboard look like a deal-breaker to me.
I do agree that its pointless to try and shoehorn a numeric pad onto a laptop as some PCs do (and push the main keyboard and trackpad off-center) but for a free-standing desktop keyboard I really can't see the downside.
However, I also suspect that most people buying keyboards will either be using an iMac or a desktop display with a USB hub in it, so I don't really see the downside of having a cable to the keyboard, either (& you get a couple of handy USB sockets on the keyboard for memory sticks and mouse dongles - great for iMacs and TB/Cinema displays no front/side USB).
They should make one. Accessories don't need to be sold in terribly large numbers to be worthwhile; Apple makes a number of accessories for niche markets.
I think the people who want a full-width keyboard (I do)
and like the aluminium chiclet keyboard style (I do)
and want it wireless (...actually, no, I prefer a wire)
and aren't inconvenient non-US types who want it in one of a dozen different layouts (guilty) is a niche-of-a-niche... and this thread has already flushed out a couple of third-party alternatives (at least for US folk).
Personally, I've got a cupboard full of keyboards anyway... although I think I've chucked all the PS/2 and ADB ones now...
