I have a Dahon Speed D7 and I love it. I used to have a Dahon Boardwalk S1 but needed to get some gears due to my hilly environment.
Anyway, it should be fine for day to day commutes. I wouldn't recomend it for any Century rides, but casual touring should be fine. A plus is that you can always fold it up and catch a ride back home. If given a choice though, I would much rather take my Rockhopper on longer distances than my Dahon , but the little thing is so convenient.
