r 18 years!!! of development, they are still productless. And they are so proud of "a proprietary, (patented) mating technique" that they seemingly forgot that it was the very open-architecture of the PCs that allowed that market to explode with products.

Note that Honeywell is still searching for a development partner after 4 years...
