I'm more cyclist than anything else and use an Oregon 600 for directions, usually following a track. The ability to put fresh batteries in and continue is what endears this type of unit to the ultra-distance cycling community. I like it's bigger screen too.
The touch screen isn't a problem with gloves, when I'm wearing thick full finger gloves the screen sensitivity needs to be set to high. You can use the normal setting with lighter full finger racing gloves.
Whether you go for touch screen or buttons is a matter of personal taste, I had no problem with the Edge's buttons, but now find the touch screen better.
