One major advantage of mbox (and now mdbox) over maildir is the time it takes to back things up for larger mail stores.
It takes much less time to compare a single mbox file that contains 20,000 messages (and rsync only the changed bits) than it does to compare read/compare 20,000 individual files (maildir)...
I too like maildir, but am seriously considering implementing a solution where older mail is automatically archived to slower/cheaper SATA III based storage using mdbox format.
