Video game audio. He does all of our audio work. Sound effects, voice over, music composition, etc. I asked him what audio he used and his answer was Pro Tools, Digital Performer, and Peak. He's got a super top of the line Mac Pro that's only 2 years old and he's been salivating at the prospect of an upgrade for a long time.

He was extra pissed that the new machines don't even have Thunderbolt. He has many hundreds of gigabytes of audio libraries on a variety of external storage devices and just having Thunderbolt would be a pretty decent productivity improvement.
