I've had the Ultra since Friday's release. I'm in love with this thing!! I really love the rugged look, and the overall size. Looks great on my wrist! Beautiful piece of technology!!
Coming from the Garmin Tactix Delta, I prefer the Apple interface, and overall functionality. My biggest issue, is battery life. I get 18 days with the Garmin, and my experience with the Ultra is 48 to 55 hours. As much as I love the Ultra, I am likely returning it simply because I am spoiled in not having to throw my watch on the charger every other day, or worry about taking a charger on vacation.
Tough to let this go, as again its a bad a?* looking device.
