I'd like to get in on this as well. I don't have a Nano yet, but have been interested in picking one up just for the Nike+ feature alone. I'm in the same boat as Entity, I can go out and slug through a couple of miles, but would like to get back into better shape this year.
For Seattle area posters who need some motivation, you should plan on running the
St. Patrick's Day Dash in March. It's a nice 3 1/2 mile race, usually a fun time.
