I just got this for my birthday and I'm excited to get out and use it. After reading through the manual I think there's a pretty steep learning curve with this watch. But the initial set up of time/day/HR was pretty simple. Used it biking, it works great.
I'll see what it's like the next couple months and report back later. I like all the Alti/Baro/HR/Compass options, also why I bought this watch. Hopefully it won't be to difficult to get it all down.
