On another line, how well has Garmin demonstrated its understanding (or
commitmant) to the fact that lifecycle of GA avionics is 20+ years? In my
opinion: not much. Or maybe my opinion is based on the above, that I don't
view the G1000 as very modular or upgradable !?!

This should be a major concern!

As an example of what can happen, I would mention the telecommunications
industry. At one time, the lifecycle of a typical telephone PBX system was 20+
years. Now, the computer networking industry (Cisco in particular) makes
telephone systems and the product lifecycle time is suddenly equivalent to that
of the computer industry. We switched to Cisco about 4 years ago. Already, we
have "upgraded" much of our hardware because it is no longer supported by Cisco
and are on our 5th generation of the operating system.

I think I can safely predict that 10 years from now, Garman will not be
supporting the first generation of their G1000 line, if they are even still in
that business!
