Awful. Terrible to navigate and I hate that I cannot see my last few activities at once on the new dashboard unless I scroll back and forth. I still can't figure out how to see the full detail of my activity with charts from the dashboard - brings me to the activities grid, then I have to click the activity. The other dashlets are fairly useless. Calendar is only useful if it's full screen so why include it on the dashboard?? Fill space I guess.
It seems like the website disappeared, was taken over by a mobile site, which looks completely ridiculous on a desktop. Epic fail. I may have to give up my Garmin in favor of something else.
