The USB works in the other direction, you plug the Playbook into a computer and access it, not storage into the Playbook?
Depending on how it was built, it could support OTG (On The Go) which is bidirectional. But that all depends on the circuit board, and if the software will even accept it. I imagine it does, but we'll have to wait for someone who has a Playbook to chime in.

Lets say you're using your playbook at work (which everyone will do I'm sure ) and someone has some files on a usb drive and wants to share them with you, this could become useful.
I'm looking forward to 8 a.m tomorrow morning to buy mine
or you could have a wired blackberry bridge which might save some battery / reduce lag from bluetooth. Or even charge your phone from the playbook in a pinch.
