The microcontroller systems we build at the place I work will run for
years on a coin cell, have lot's of processing power, and run about
$20.00 parts cost. And, no, there is no way in heck I am going to trust
my life to MS winblows or to any consumer electronics! I know just a
little too much about how the consumer electronics industry works!
