Actually, I think they have the mindset, but don't understand the ergonomic
factors that can be encountered trying to use it.

For example, I've twice been cleared to random 5-letter fixes which do not
appear on enroute charts that turn out to be IF's for ILS approaches. These
clearances were issued en route, 60-100 miles away from the airport, well
before an expected approach had been specified. Actually, both approaches
ended up being visuals. I don't know every 5 character permutation of
"wip-pee" intersection and which one applies - running through the guesses
takes some serious knob time. Yet there's always a certain irritation
(noted by the poster as well) in the response to the request for
clarification, the spelling in my example.

Maybe a screenshot of a Garmin 430 with intersections and data fields
represented on the 100nm scale will help to convey the problem.

Sounds like you did the correct thing. It is going to ATC awhile to adopt
a
GPS mindset.
