I just did a quick search and found this article some what interesting:

As for those security points an easy solution would be to have a specific Blackberry model with a camera only. Or, it could be detachable somehow so that if a person needs to go into one of those security tight areas it won't be a problem.

I agree that removable media is a security hazard, but flash media is growing increasingly cheaper so future devices should have much largest built in storage capabilities. Heck, I still use a Yepp-64 MP3 Player (64 mb flash) that I bought 5 years ago and it holds enough for my needs.

One business use I can see for MP3 capabilities is for recording studios. Since most project studios record in strictly digital it is quite common to proof mixes via email as a MP3. This could have come in handy for me in the past, but not nearly enough to be a selling point. I could also see uses for proofing radio spots for advertising agencies.

Providing the hardware is already up to par, I would think MP3 integration should be quite simple. Cameras on the other hand I can understand why there would be resistance to modify the hardware.
