The days when Model M keyboards were a common sight at thrift shops are gone. I presume most were donated by businesses that retired their PS/2 computers, and got new keyboards with their new computers.
So Unicomp can thrive doing what it is doing now.
But if I had been running the company, while I would understand the need to keep tooling costs in line, I would have considered it worthwhile to manufacture what people can't find on the used market.
I would have made buckling spring keyboards for Sun computers. (Sun's license fees are reasonable.) Now, of course, what with Oracle's acquisition, that's probably not worth bothering with.
I would have made buckling spring keyboards for the Mac.
And I would also have indulged myself recklessly by making a 122-key keyboard in which the main typing area is laid out like the one on a 101-key keyboard instead of the one on a 102-key keyboard.
(Other weird characteristics: it would be switchable between Host Connected Keyboard-like scan codes and an alternate set like the one they offer on the PC/5250 - I would not have made a product like the PC/5250 without the option of switching back to HCK behavior, and it would have 125 keys, so that when the computer is not being used for 5250 emulation, the Windows keys would be available.)
EDIT: I would also have at least given consideration to what is particularly desired by many here - a buckling spring compact keyboard; perhaps a plain one with laptop styling... or even a partnership with Fujitsu to create a buckling spring version of the HHKB if possible. (Actually, looking at their site, I see that while the Mighty Mouse is 'discontinued' in its main version, the one with the piezo pointing device, the version without it is still advertised as available for $99. But it doesn't have a version with Windows keys, so, yes, there is a lack to remedy.)
I see they do sell point-of-sale keyboards, but not ones with programmable keys. That is another key omission from their product line I would address.
