I just ordered a Garmin 800. Reading the reviews and capabilities of the device it looks like it has many more features than I will ever use but looking forward to utilizing some features. One thing that's disappointing is that detailed maps will cost extra. One of the reasons I bought it was to be able to map out rides, destinations etc There is a way to get some free maps and transfer them via mini SD card to the device but I would have thought that for the price, detailed street maps would have been part of the device.

I would be interested to hear from those who have used this unit for a period of time. Which features do you find most helpful/useful. What is your overall satisfaction or dis-satisfaction with it etc.
