[Wear-Hard] the best display for some is not sold.

[jon sable]

my hobby is wearable computing,   and microopotical produced a solution, 
see "tads" usage of a display built into corrective optics...


it cost 5K     at the time,  looking back that is cheap for a   covert 
display system and prescription lenses.   So tell me/explaine the reason 
why its so costly to have a covert system?


the technology was there, the application was lacking...
