The frank answer to the original question has to be "No."
I've managed 30+ miles in the day on one with no ill-effects, the luggage carrying is excellent, the handling is a bit iffy, but probably no more so than any small-wheel machine. Mrs. Wow and I each have one, and they get used in preference to full-sized machines for certain purposes, notably when we don't want to leave a bike outside somewhere or other.
Of course, if I commuted by train it would be used every day.
