I've got longer out of the 800 but not while using navigation. I think it's the combination of using navigation and doing 3-400k+ that kills the older Garmins. So far the 1000 has been much more stable than the 800/810s but the nav is shit and the screen is annoying when wearing gloves. Oh and battery life sucks.
I've actually found the navigation on the 1000 way better than my old 810, but it did take some tweaking. I'll add my settings to the thread when I get home.
