Their down side is expense, and slow speed handling IMO, but they are great for back issues, and long distance rides.
I borrowed a recumbent for a while several years ago and found it an interesting experience. I can understand that it would be ideal for a weak back, but I gave it back after failing to get up any of the rather steep hills around here.
I'm on a Trek520
