Anybody have any experience with a Bike Friday tandem?

I'm thinking that in my constrained little universe a folding tandem is probably the best way to go.

I've known one couple who had a BF tandem and absolutely loved it, rode everywhere on it, and had no transportation or storage issues.

Storage is a big factor. I've got bikes in the kitchen, in the closet, under the stairs, in the bedroom... any tandem I get (someday) will have to fit inside my 990 sq ft apartment. With all the other bikes.
