Great to have offline maps, 3D display

I used this in the Grand Canyon recently, where it was great to be able to use it with no cell service, after downloading the maps prior to the trip. Most of the hiking trails showed up on the Topo II maps, and the satellite photos were really amazing, especially I 3D mode. Ive also used it around home for tracking mileage and elevation profiles for training hikes. It seems to be more a accurate than my Garmin Edge for this.
One thing Id like to add is the ability to merge maps of the same type with partially overlapping coverage areas.
