GPS Models -- Pros and Cons

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.

Thanks, you're right. Does that also go for built-in aviation GPS's/Moving
Maps? I assume there is some sort of certification there?

Last advantage I can think of is also a disadvantage: you do not pay for
certification of the equipment (I'm sure Garmin and others have some
percentage for that in the price)

Nope. Portable GPS's aren't certified.

Yes. There are various levels of certification for units installed in
certified aircraft.
