Now I'm guessing you are talking about the Playbook
"4. Absence of USB mass storage port
Surprisingly, the BlackBerry PlayBook doesn't have a port for USB
mass storage device. Although a storage device can be used on it
indirectly in a complex way by using a feature called BlackBerry Bridge,
it is inconvenient if you want to just pick one file. BlackBerry Bridge
is the only 'interesting' feature the company can put forward to the
public. It allows the user to pair the tablet with a BlackBerry phone.
This will enhance the security for the user."
You should discuss with RIM how to put files on and off the Playbook with ease.
