I remember seeing ProTools and other audio workstations around my city still running on old 68K Macs for years after the PPC transition because they worked, had crazy-expensive licenses, and were treated more like racked equipment than traditional computers.
Absolutely. That is more the rule than the exception for professional recording studios. Still happening, too. If you bought into many thousands of dollars of gear for Thunderbolt, for instance, or FireWire, the computer is only one small piece of that system, and becomes part of the racked equipment.
Yeah, audio/musician guys I know were using PowerMac G4 towers years into Apple's "Intel" transition. And yeah, "upgrading" means basically tossing away a perfectly good $1k piece of software and paying nearly as much for an upgrade license.
