I guess I was thinking more along the lines of beater/commuter really.... I mean, who the hell cares how much it weighs, etc when its just supposed to get you to/from work or class. I've converted my mountain bike to a commuter for the time being, but I'm definitely getting one of these to save wear and tear on my good bike.
As for the rust issue, simply coat the inside of the frame with
Weigel Frame Saver Spray and you'll never have to worry about rust as long as you retreat every few years or so. Believe me, I've owned nothing but steel road bikes over the last 10 years and this stuff really works. It's impossible not to get caught in the rain during the summer here in the south once in a while.
