I love hearing you all be like "this blows, I'm sticking with my Garmin 800 (810)."
Dudes, I am still riding my Garmin 705!!!! From like 2008. Works perfectly fine to this day.
No battery issues.
Water in USB?!?!? Someone said that, sure maybe, but the little rubber thing went on mine years ago and I do a fair bit of rain riding - no issues.
All features still work. I've downloaded routes and risen this bad boy for 6k every year and it still works fine.
We did a century last automn and the ride leader, also the route guy, couldn't make it. Downloaded the same route from the year before and the entire group did it following me. The 705 - this "old" unit - did it with aplomb.
I will say this, Garmin makes stuff that lasts. Doesn't look good, but it lasts. The map/route feature has saved me a ton and I've downloaded routes all over the place and done them not knowing where I am. Yes, an iPhone works too, but it drains wicked battery, can't mount too well (unless you have a mount) and just kind of stinks (apple maps stinks - google ok, and waze useless on a bike).
Anyway, just thought I'd throw that in - Garmin makes good stuff. Though this thing looks to be wicked big.
My 2008 Edge 705 is still rock solid! No issues whatsoever! Maybe the battery did loose some longevity, I did lots of Audax in 2010-2011 with some 20h rides and the batteries held on just fine. Last month I was out on a 9h ride and got the LOW BATTERY warning 13km from the finish. Nowadays I have a powermeter and use 1-sec recording, but Garmin says it won't affect battery drain. Ordered a more powerful battery and will replace it next week.
Regarding the Edge 1000 or even the 510/810, they just don't stand as an option for me. Nothing really great to justify the premium $$$. I would gladly upgrade my 705 for something in the 500 form factor, with mapping functions and full powermeter support with extended battery life. Maybe the SRM PC8 will bring it all together?
