Navigation through menus is a bit clunky coming from an 820. As I can easily work it even with heavy gloves though, the trade off seems ok to me.
Everything else is fantastic, not counting one train wreck of a bug.
LiveTrack, EVERY time I ride, times out then fails to launch and proceeds to tell me so with a beep and on screen warning every 30 seconds for sometimes an hour or more, which is possibly the most anger provoking bug I've yet encountered in a Garmin device.
Sometimes LiveTrack eventually starts working, calming my wife and me by extension.
It's enough I may have to return it and try something else or just never use LiveTrack.
