One would think there might be a sizable market for a bluetooth, n-key, buckling spring (or blue cherry) board available in a variety of case/key color combos (including black) and with the classic 84/101/105 key layouts. It's pretty clear from this site that those are the most demanded features, but for some reason, they're completely unavailable in a single package. Sure some boards come close; the Deck keyboards would be awesome, but they opted for the non-clicky linear cherry switches and a bizzaro space-saver key layout; the Das III looks promising but apparently lacks true n-key rollover support, has no bluetooth, and no space-saver layout.
If a manufacturer could just put these things together I think there'd be *a lot* of interest from the hardcore gamer/coder crowd.
Alas, Unicomp's access to the buckling spring and original M board designs that would be an excellent starting point from which to develop something like this, but they do not seem to be in the innovation game at all. Unicomp's business seems to be milking the basic IBM keyboard designs for all they're worth, but I bet they have almost no resources devoted to new product development.
The "high-end"/"serious user" keyboard market amazes me, the requirements are pretty basic and well known, but manufacturers mostly ignore these and focus on adding craptacular secondary displays, multi-media keys, and the like.
Shame really...
