I got one today.

A big improvement over the previous gen (Garmin GPS V), but probably aimed at different markets. They fixed several issues I had with the GPS V but introduced many new flaws.

The biggest improvement is the ability to have maps on SD memory cards. I am able to store detailed maps for all the locations I usually visit during the year on a 256mb card. NY/NJ, Boston, Central Florida, Houston, LA, San Francisco, Chicago, Hawaii...

Some pros:
-Route calculations feel about 10x faster
-Great color screen with virtual graphiti area
-SD memory expansion (32mb built in)
-Talks in multiple languages

Cons:
-Palm based
-Requires stylus use for many functions, this might be a problem while driving
-Battery life is very short
-Not water resistant
-Power and data connections appear to be delicate
