Can I use the BeOS as a media workstation OS (for example, replacing MacOS for MIDI or SGI for video work)?
You will. BeOS was designed from the ground up as a high-performance media-oriented OS, with a high-performance 64-bit filesystem, full memory protection, and native support for multiple processors. While there are few AV apps currently available, there are some interesting ones under development. Because BeOS is the natural choice for the next generation of media applications, as more developers realize this, applications will follow.
