What I still like to use a dedicated GPS for is for georeferencing the photos I take while out mapping. My camera does not have a built in GPS and I prefer to use a dedicated camera over my phone camera which would yield georeferenced images.
And maybe even more importantly, to upload the traces to the OSM server (although I badly need to catch up with that). I think that will always remain useful.
