Does anybody have one of these? If so, what do you think of it? Like it/love it/o.k. but not as good as _______ - ?

I'm looking at this as a commuter/errand bike. I've seen their online demo and like the way it folds and unfolds quickly, like the idea of being able to take it inside the grocery story, etc. instead of locking it outside, like the idea of carrying it on the bus or in the trunk of a car, etc. I've read a few reviews but would be curious to know if anyone here has one.
