For a company with non-existent marketing manufacturing for a niche market, this is not easy.
And, of course, the other problem is that
we're not the niche they're manufacturing for.
Their core business is corporate customers which used genuine IBM/Lexmark product in the past and wish to remain with it. Like the Japanese corporate customers of Topre, they presumably have found that a quality keyboard reduces typing errors and increases speed.
So, they
did go to the extent of making a modified full-size keyboard with Windows keys, since their corporate customers would want to keep up with the times to that extent, but a tenkeyless is mainly a home enthusiast sort of thing.
At one point, based on discussions here of their limitations, I had thought that perhaps they could just change the electronics, without changing the mechanical design of the keyboard, and produce something interesting based on the terminal keyboards with one extra key over the 101/102 key design. But it's their keyboard with Windows keys for which they offer some custom preprogramming, and they have no dynamically programmable keyboard at this time. (That is a common enough point-of-sale product, I'm actually surprised they haven't branched out to that.)
