With a class you have reduced the reusability of all the functions ("methods") by locking them to a certain type of data structure. This may, in the short term, make them easier to use; but the lock-in nature dooms them to obscurity.
Right on, and this is not discussed enough. I know this is not really a problem with OOP - per se, and can be mitigated with refactoring, but this is a problem with re-use. Software artifacts should be loosely coupled with tight cohesion. When you throw everything in a class you end up with tight coupling a lot of the time.
