I've flown with an Avidyne Flightmax for a couple of months, before we
upgraded to the EX550. It ran WinNT (3.51 IIRC) on a PIII. It froze
every week or so during normal use and I got the Blue Screen of Death a
couple of times. Wasn't very reliable... I think we went through three
replacement units (All on warranty) before we finally got the 550.

The EX550 is a lot better, only freezing twice so far while acessing
airborne radar, according to Avidyne a problem with the Radar Interface.
I don't know if the 550 is still running WinNT as the boot screen no
longer shows any information about the underlying OS. The current one is
the second Unit though...

Cheers,
Jens
