I have a Garmin eMap that's a few years old and while I'm not quite
ready to replace it, I still look at the new models from time to
time.

Other than additional user features, some of which might actually be
useful to me, are there any non-visible improvments, such as better
receivers, better antennas, faster, more accurate position
computatation, etc?
