I agree that one size doesn't fit all but I disagree on the mountain bike. Not only do I use one for 10+ mile (one way) commutes, I do them with knobbies on the bike. Nothing freshens up a commute like a little variety and I use the mountain bike to off-road to and from work. Yes, it is slightly slower but that's not the point. Doing something different and maybe having some fun is the point.
