I haven't seen these yet:
* The ability to chose a specific level of map detail that would be maintained regardless of zoom level. Garmins have this, and this is one thing I really would like...when I zoom out on my 720, I only end up with a couple of roads displayed - I'd like to see more to form an overall picture of my position as related to the major roads around me.

* Here in NC, when approaching a cross street, many of the secondary roads show up as the state road number, rather than as the actual name of the road.
If you turn onto the road, the correct name is displayed. This can be maddening if you are looking for a street name prior to a turn, and all your GPS displays is "Hwy 1720", rather than "Maple Ave"...and its telling you to turn on Maple.
I haven't been out of state with my 720 yet, so I don't know how it would act elsewhere.

When searching for a POI, its relative distance is given in "as the birdie fly's distance", but when you select it as a destination, you are obviously given the resulting distance as you would drive it...the difference can often be great - especially in hilly terrain.

Thanks MVL!
