Another significant downside to the interface problem is your
head-down time. The amount you spend looking inside with the PDA vs.
the GPS will be greater.

Not necessarily.

Using just the moving map display on both units, for example, will not show
a difference in head-down time.

Depending on the type of activity you're doing, either unit can cause more
head-down time than the other.

The fact remains that the only way to truly evaluate the difference is to
take a flight with both units.
