True.

This isn't meant for the user, though. This is meant for the developers. No matter how hard the developers try, users will always pick bad passwords. If you use salted SHA-1, then if the database gets compromised there goes 50% of the passwords. If, on the other hand, you use bcrypt, maybe only 5% of the passwords get cracked.

Bcrypt turns a massive news event (database leaked; thousands of passwords lost!) in to something much less newsworthy (database leaked; twenty passwords lost).
