I used it on a plane once, like 5 years ago. I recorded something like 350 miles per hour and 24,000 feet elevation. The stewardess told me to turn it off when she saw me holding it up to the window. I didn't argue, even though I knew it doesn't transmit, just receive.

Yeah-- I have a b/w Legend and it's not safe for driving. Too small, not enough detail, too slow to use for point of interests while moving at car speeds. In the car I pull over and use it for "Where am I?" Not for "Where's my next turn?" while moving... But I agree with others, handhelds are fine if you have a partner. Although mine needs to be near the glass to get a clear view of the sky. Also--the older b/w Legend does not have any memory card inputs, just in case that's what you're considering getting.

FWIW, I have the eTrex Legend, with a Dynex/Prolific USB adapter. Seems to work with GPS Mac Pro software. But not with the Webupdater software. Using a PPC Mac Mini.
