Familiarity: I've put it through the wringer
Been using this watch since Christmas 2012. Mainly I use it as a trail running watch, but also on a few winter hikes in the Appalachians.. It grabs the signal pretty quickly and is very accurate (after I updated the software). IMPORTANT to keep the software updated.
If you are just a runner this probably isn't your watch. If you Hike, Hunt, Run, etc - this is your huckleberry. I like the Garmin Connect features which allow you to share maps. I was talking to a guy about a trail that we run and I was missing a turn that would take me on a longer run by the river. After about an hour of, "you know where it gets sandy - just after the power lines..."he just sent me his route and I saved it on my watch. Very cool and practical.
I look forward to using it more for hunting and winter backpacking this year. I will be carrying my JOOS to keep it charged while in the backcountry. When in GPS mode it can suck the battery.
Hope y'all find this helpful.
