Summary: I bought this unit with the intention of riding my bicycle across the Swiss and Italian Alps. Didn't want to use a paper map. The unit performed very well. If you're reading this, you're probably thinking of buying one of these units. There are a few very important things you should know that Garmin does not make abundantly clear. First of all, the unit comes with the most useless map ever. They call this the "Base Map." It only shows freeways and major cities.
Summary: This cycling computer is a great addition to my bike but it is very hard to see the screen on a sunny day. Like all the Garmin products its position and calculation features are accurate and easy to understand. The touch screen works as advertised. If the screen was easier to see in all light conditions I'd give the product five stars.
Summary: I have had this for 6 months or basically one season of riding. My wife bought it for me as a birthday gift for somewhere in the $500 range. Gripes: 1) Map went out of date in less than 3 months. That was an extra #60 bucks I had to pay after receiving the gift. Why that can't be part of the base cost, who knows. About the 3 month out of date map, Garmin basically told me, yea it happens and too bad.
Summary: This device quickly reminded me why Apple devises are so ubiquidous. My iPhone and IPod's screen are razor sharp. This Garmin has a pixilated, very low resolution screen. The location triangle isn't even straight lines. It's like using an old school Atari screen. Battery life is good. It's frustrating that I pay $450 and still have to pay more to get more detailed maps.
Avoid the Bundled Software! EDIT 5/12/12 -- Unit Recalculates Your Own Routes!

Summary: Bought the bundle (which includes the City Navigator North America software on an SD Card) at the beginning of this month (April 2012) and was unpleasantly surprised to find out that the included version of City Navigator (2011.40) was over a year old (from January 2011)! If you go to the Garmin web site, the most recent version is 2012.40, which came out in January 2012.
Summary: This is no 5 star item. I have had several bike computers as well as an edge 500. It likes to lock up on occasion. You will at some point lose your data, hard resets this, soft resets that. But, when it does work, it does a terrific job of mapping, directions, points of interest, and provides great training opportunities. It just is not 100% reliable, and for this amount of money it really should be. I would not buy this again at this price point.
Summary: Great cycling computer but poorly manufactured. Within 2 months after purchase the wireless speed/cadence sensor went bad. I replaced the sensor then 2 months later I accidentally tapped the touch screen with the bottom of my bicycle shoe. The touch screen shattered but the cycling computer still worked. Customer service offered to fix the 800 edge if I sent it in and paid 99 dollars.
Summary: I've had this unit for about a month. I cycle between 100-200 miles per week depending on my schedule. Before I was using an Android phone with MapMyRide and AllSport GPS at the same time. While this review isn't about those apps, they do almost everything this Garmin does with the exception of turn-by-turn directions when using .TCX files and cadence (the MapMyRidde app can sync with a heart rate monitor).
Summary: "Garmin External Power Pack" labeled as compatible with many Garmin devices. But it is mostly for "Edge" models, yes it is compatible with Forerunner 310XT, but with 3-4 different adapters ;( In general I fell like this product mostly for bikes.
Summary: I've had the Edge 800 for about 3 weeks now. List below is what I remember, and not in any kind of order. I'm sure there'll be more as I use it further. Dislikes: 1) Not enough functionality for the cost. ...a) Could not disable custom map. ...b) No detailed reviewing of training. Have to download to website or PC. 2) Not totally lockable screen, 3x touch will show a dialogue box which is annoying if you put it on your pocket. 3)* Garmin maps are incomplete.
