I ride 6.5 basically flat miles each way to work, year-round, in all weathers. Such riding, and the concomitant errandizing, is one of the perfect applications for a singlespeed.
The Raleigh One-Way is just such a commuting hack. I bought it last year on Craigslist for a coupla-hundred bucks and rode it the way it was (basically stock) and just replaced things as they either wore out, broke, or annoyed me too much on a daily basis. It’s really just another frame that’s easy to hang some of my stand-by stuff from so that I can ride it every day without having to think about it much. And that’s all it needs to be.
I carry everything I need (and quite a few things I don’t) in a Misson Workshops Vandal or (as pictured above) in a Carradice Lowsaddle Longflap.
