Its an all electronic ADI with EFIS display. They say they are
currently engaged in certification. What do you guys think about
the prospects for use as a primary AI for a standard airplane like
my 172N ?

I emailed them, they said it would be ok after they get certified.

This seems a damm sight better than my idea to upgrade to an
electric AI. Its fully self contained, having its own inertial
and GPS guidance, and even has a mangemometer for compass heading
that is gyro stabilised.

These things work internally by having accellerometers to sense
direction change, then use the GPS to "upright" the inertial
calculation, which is one reason why it needs a built in GPS.

This means it has no rotating parts whatever, cannot spill, etc.
