Just noticed this thread. I really dig the Edge 1000.
I've had other non-Edge Garmin models before, but this is my first Edge device and I wish I would have bought it sooner. I did a 5 hour ride not too long ago and had plenty of battery life left at the end of the ride. I want to say it was around 56% at the end of the ride maybe.
I do like the segments, turn by turn nav, wifi, ability to build workouts and of course the larger screen, but I'm sure I would be basically as happy with the 810.
