[Blindmath] RFB pricing was RE: LaTeX and Nemeth

[Neal]

The following represents my own personal opinions and in no represents any 
organization, commercial or not-for-profit.

I am not sure of the pricing outside the USA, 
Perkins Products sells the 
Seika3 40 cell braille display for $2,495
Seika3 80 cell braille display for $3,900
I realize this is still much more than the price for a cup of coffee but it
is a start.

It is interesting that one company lowered the price on their 40 cell blue
tooth from about (I may not be correct on these?) $4,500 to about $2,900.
It sure seemed like a reaction to the Sieka pricing.

I have been convinced by several others that there is essentially price 
fixing in the market for braille displays, which has impeded innovation 
for many years.  Bendors of braille displays sell them at prices that 
individuals cannot afford, but it is profitable to do so because they 
know that government agencies will pay almost any price when buying such 
an accommodation.  Compared to technology development in almost any 
other area braille display technology has been stagnant.  We need to 
find ways of breaking this destructive cycle so that true competition 
and innovation in braille technology can flourish for the benefit of 
blind peopleh!
