When the effective price difference between Smoke on OS X and Smoke on Linux is at least $40K (if not more), it becomes a Very Big Deal Indeed for a certain subset of the post market.
To be blunt: For this particular market, FCP X will never cut it. Smoke is pretty much the only saving grace of OS X at this point. If Apple kills off its most capable hardware (the Mac Pro line) for the market that would invest in Smoke, the Deal Is Off.
Autodesk’s own employees and evangelists will freely admit that Smoke on a Mac Pro will trounce Smoke on an iMac. Furthermore, the Smoke gurus (Grant Kay, etc.) will freely admit that Smoke on Linux trounces Smoke on OS X on ANY currently available Mac.
Let’s be clear here: Apple has removed (or will soon remove) itself from being a player in the high-end post market as far as its hardware offerings are concerned. As a result, a certain subset of users will be forced to embrace either Linux or Windows systems if they want to remain competitive from a price/performance perspective.
Apple is doing very well, financially speaking. Will users’ allegiance to Mac OS X follow suit? Or will users’ ability to embrace new technology and adopt the current best solution for the job define their future?
