The screen on the Garmin Edge 800 is the most disappointing part of the device. There's rumors of an Edge 900 being released in the not too distant future, maybe at Eurobike in September, and I hope the screen is the thing that they focus on. On my 800, I don't like it to give me turn-by-turn directions - I just generate a GPX file using mapmyride and upload it to the device, then set the settings to always display the track as a solid black line, then I just follow the line; if I decide to alter the route while riding or if the plotted route is not what I intended, then the device doesn't give me any warnings about being off course, so I prefer doing it this way.
