Hopefully Unicomp will pull it's head out of the stand and realize it can start competing!
Well, where does the money come from? For mechanical keyboards, the PC gamer market is full of potential. It's a lot easier to market cheap imported keyboards (Razer BW) with gamer-esque styling (Razer), additional macro functionality and established minimum conventions (NKRO, polling rates, etc, whether justified or not). Unfortunately, Unicomp essentially bought the patents and designs from IBM and stuck with it. None of their models feature the above requirements. And nor does the company have the means to undergo both R&D and marketing for new, improved keyboard designs with modern usage (gaming) in mind.
Without a spark of broad interest and a company willing to take the risk, buckling spring keyboards will continue to be niche, nostalgic artifacts. Cherry MX, more interested in selling electrical components than building keyboards, is more than happy to allow their MX switches to be used everywhere for any purpose.
