i have a business use for an MP3 player: I am stuck in airports all the time.

Can't question the security rationale, because I am simply not that smart, but I don't agree with the argument that "this is a business device, not a toy" because the blackberry's come pre-loaded with brickbreaker and can download hundreds of games. I most definately use my BB for business, 99% of the time, but nothing wrong with killing boredom when on a plane, in a hotel away from family or on a dull conf call.
