Pocket FMS
I'd be very interested to hear how Pocket FMS compares with the likes of a Garmin 96c...in the market myself and read plenty of opinions from a couple of years ago about mobile phones/pdas etc. being too flakey to run Pocket FMS as anything other than a backup GPS but would prefer an all-in-one type solution a pda/phone might offer.
Counting down the time until the iphone offers a workable aviation-style GPS!
