Just posted a huge (>1 hour) video of the 620; the first (of 4 parts) is at https://www.youtube.com/watch?v=F6jWSFbhXP8. I ended up buying the device when it had been sent direct by Garmin. I am mainly in love with it, my only caveats being that there is no Virtual racer, and you can't create advanced workouts on the watch (as opposed to using Garmin Connect). Otherwise, highly recommended.
