Finally upgraded from my Garmin 705 to a 520.
No more plugging in my device!! Which sounds simple, but I the VM I was using didn't always recognize it, and I had to upload the file twice (once for WKO, once for Strava).
Now it all just automagically syncs, no cords involved. And using WKO4, I don't have to upload it there either. More time to post meaningless stuff like this!
Wko4 is still annoying and confusing, but I figure I'll get the hang of it after a week or so.
