I love my Garmin Edge for local solo and group riding. I get to geek out on all the stats.. elevation,HR,Cadence and so forth. Including being able to see map details of my rides.

With the above being said... On tour it would be a pain is the butt. For one thing you need to have a computer to upload all the information or it just stops recording the details. When full it is nothing more than an overpriced basic cycling computer with GPS. You only have so much memory in them. If I toured with a net book maybe I would feel different. Since I don't tour with a net book it just ends up an expensive cycling computer that uses lots of power and that has to be recharged via usb or usb/ac. Fine for short tours but... You get the idea.

If I really wanted GPS while touring I would get a Garmin that uses AA batteries. Easier to deal with. Batteries last much longer as well. Plus I would just turn it off when I didn't need it. If I turn off my edge computer I record nothing. So I'd still need a basic cycling computer to keep track of miles.

So...... I'll stick with my Planet Bike wireless. Past experience tells me that I may have to change batteries over the course of a 4000 mile ride. Can be found in just about any drug store and I'm all set again. I've never had a problem with wireless using all that many batteries and they are cheap.
