A terrible device with zero customer support that you'll buy anyway, because there's no other options yet.

Summary: First of all, if you're looking at the 810 versus the 1000, I'd go with the 810. If you're even looking at the 810, I would go with the 810. The 1000 is too big and the non-resistive screen is too sensitive. If you're looking at the 810, I'd go with the 810 because there isn't really a competitor, yet. (Come on, Magellan!) That said, the 810 may have the worst software both in terms of UX/UI and reliability I have ever used on any product.
Summary: I received the item and have been overly frustrated from that point on. To begin with the spoke magnet clamp came in broken. The Heart rate monitor is not transmitting. I have done everything in strict accordance with all supplied including the manual that I down loaded and printed. To spend 700 bucks and have it come in with problems says a lot for QC at Garmin.
Summary: We ride to relax, train and vent, and we expect equipment that helps us instead of adding to our frustration. I’ve used each generation of Garmin Edge products, moving up to replace defective units, or because Garmin promised better battery life or improved interface. In each case, I’ve been disappointed.
Summary: Terrible device. This thing costs more than any of the other multiple Garmin bike computers I've purchased in the past, yet it is the worst electronic device I've ever owned. I've probably been on 30 rides with the computer. It's failed in one way or another on at least 20 of those rides. If you try the "live track," you are guaranteed to fail.
Summary: Just bought a Garmin Edge 810, and I wish I could write a comprehensive review. I purchased this model to be able to use the map and navigation features. Right out the box, I realize that I had not carefully enough read the fine print: To take advantage of the routable map feature, it is necessary to additionally purchase the maps from Garmin. Shame on me for not being more careful. So I purchase the US map package at Garmin's website for immediate download.
Summary: I have had terrible luck with the Garmin 810 which I received as a gift in April. This is my first experience with Garmin. If I change screens during the ride, the unit freezes up and is worthless for the rest of the ride. One time I touched the screen to wipe off a smudge and it shut down 4 hrs into a ride. I have done the most recent upgrade and it hasn't helped at all.
Summary: Happy with Garmin for year. Liked my 705; loved my 800, but completely disappointed with the 810. If you used to the 800; don't upgrade. At least don't upgrade yet (Firmware ver 2.2 as of January 2013). The unit is VERY bad. It crash mid rides. It sometimes report wrong elevation. the new Bluetooth ability to upload the file fail 50% of the time (and it only work with Garmin connect...
Summary: Having used this for about three months now, I'd have to agree with everyone who's saying it's not ready for prime time. Especially disappointing since it's a replacement for a device which is widely respected and (apparently) stable. I'm having issues which range from spontaneous crashes (just turns off without warning, reboots) to crashes prompted by swiping between screens (several times now).
Summary: I have used the unit on 5 rides and had problems on 2 of them. The first time the unit just shut down for no reason that I could see. It powered back up and continued function properly on that ride. The second round of problems was definitely more serious. I went for 100+ mile ride. After stopping for lunch, the unit wouldn't power-up past the initialization screens. After 5 or 6 hard resets, the unit functioned for a few minutes and then locked up again.
