Okay, after investing another $115 in map pack and memory card

Summary: I loved my Garmin Edge 800, and this is easier to create bike and training profiles, and allows you to quickly change between road riding and trail riding navigation. But my big problem is that it doesn't come with any useable maps installed. And after spending an additional $79.99 to buy the North American city maps, I found that the Edge 810 didn't have enough memory to install the maps. So I'm back on Amazon buying a memory card for another $35.
Summary: I've had the 810 for about 3 months and about 1,000 miles worth of (road) riding and can finally put a review on it. Plain and simple: If you want this for the new "bluetooth" features, forget about it. Unless you do 20 mile rides and less, it's worthless because you will have a dead phone and a dead 810 battery. Pros: Screens are easy to navigate. As well as setting up the device. You can see it fine in the sun, I don't know what everyone else is complaining about.
Summary: Well constructed, but battery life has not matched manufacturer's claims (12 hrs vs 17 claimed) and that will only degrade over time as will all L-ION devices but since this is a sealed device that becomes a bigger issue. Bluetooth 2.0 is disappointing and the connect via cellphone feature is beta quality.
Summary: The Garmin Edge 810 is nice. I was torn between three stars and four. The device itself is very nice. Battery life, with GPS running, is solid. The screen quality is pretty decent, but it's not a sharp high-res screen that you're probably used to from things like your cell phone or tablet. The first one I received had a dead pixel right in the middle of the screen, which is just one of those things that once you notice it, you can never _not_ notice it.
Summary: I have had a superb 4 year experience of the Edge 500, and hesitated about upgrading as I understood there were some reliability issues with the 810. Unfortunately this is my experience too, and I am kicking myself for not researching reviews across websites more thoroughly - having done so post reliability issues I release the problems of screen freeze and the touchscreen failing to function are not uncommon.
Summary: I bought the 810 to replace a nearly 5 year old 705. Back in '09, the 705 was a revelation for me. Being able to navigate and load detailed training plans was fantastic. Being able to discover new routes in unfamiliar areas opened my eyes. It was however, a very clunky device with some frustrating limitations that seem to have been addressed and refined in the 810.
Summary: Could have been amazing but was very buggy (temperature and calorie readings were unusually low and frequently crashed). May have been faulty although a number of forums suggest that the current model is riddled with issues.
Summary: Pros: Its a GPS, with mapping and will allow you to record your rides or guide you through routes you have uploaded. It can be mated to an HRM belt, cadence/speed and power sensors. It seems to be pretty accurate. The mapping is decent. The Garmin Connect service allows you to find routes and make routes reasonably easily. Battery life is signifcantly better than an iPhone 5 running software that does similar stuff and it takes up much less real estate on your bars!
Summary: I own a Garmin 500 and Garmin 800 which I have been using over the last two years, so rather than being a newcomer's review, I am writing this from the point of view of someone who has owned and regularly used Garmin units, and who has come to have certain expectations on how things work. At the time of review of this software, 2.30 is the latest firmware available for the 810.
