I've used the 800 for touring and love it. I pre-load the route with TCX files. I use OSM maps designed for cycling. It's best feature, when used with a route, is that it tells you immediately when you're off route. I hate having to stop and look at a map to figure which way to go, and also hate backtracking. The 800 is a good solution. Not perfect, but as good as it gets right now. Works in any country, any time, no cell tower access. It just works. I use a battery pack of 4 rechargeable AA cells to extend life, and carry an extra 4 cells. Battery life thus is not a problem unless one is really remote, doing MTB touring in Africa, for instance. In which case, one can use a hub and a USB charger device. But not necessary for ordinary touring. I don't carry paper maps any more. I used to, but never used them.
