I am partial to stateless sessions, but I know plenty of otherwise normal
people who strongly prefer the programming model implied by stateful session
beans, often out of habit or for aesthetic reasons.

You think that's bad, what about transaction settings? At least with
stateless/stateful, the bugs caused by incorrect deployment would be obvious
very quickly. ;-)
