The biggest problem I have with this is that no other software exists with such easy-to-use tools for importing GPS tracks, creating custom points, and exporting KMZ files for share with other people. I use it a lot in my work to track routes to rural locations, POIs, and calculate areas. Additionally, all of these important features work offline using cached maps. While QGIS is incredible and powerful, it is too complicated sometimes; if there were something in between, I would be pleased.
