There
is no proof at all for the claim that some straightforward math calculations
in any GPS software is going to to double the cost of the GPS.

Have you ever written software?

If it prevents one death that results in a multi-million dollar lawsuit, it
would payback the one man-month of work it might take to do those
calculations in software 100 fold or more.

It is actually more likely to =cause= a death - to a pilot who decides
to rely on a handheld because it has RAIM.
