Yes. I ride a geared carbon fiber road bike on weekends but for commuting I prefer the simplicity of my steel single speed with rear rack, front basket and bullhorn handlebars. Yeah, you are frequently in the "wrong" gear but that just kind of keeps it interesting. I have to get out of the saddle for hills maybe half dozen times on a nine mile (one way) commute and I have to go slower than I prefer on other sections.Since the majority of my commuting is in the dark this doesn't seem like such a bad idea. Also after riding hard on weekends being forced to go slower and "smell the flowers" is appealing.

Part of the experience I like is having a bike where you just throw a leg over the bike and go, like when you were a kid - no specail shoes, no spandex. I know you could do the same with a geared bike, but for me it's just not the same.
