I think Apple is skating to where the puck is obviously heading for content consumers. I think they have missed the puck when it comes to content creators.
I get that young people are very adept with the tools they have at hand, but there really is a big difference between what is required to create a YouTube video versus a major motion picture, and I'm not seeing that gap diminishing significantly with Apple's current offerings, or particularly with the direction they are taking their software and hardware. It seems much more consumption oriented, not production oriented.
I am neither agreeing nor disagreeing with you, but I have heard that before.
I can't do a complete audio production on an iPad, I need my MacPro for that. No argument there, but let's back up here.
As little as twenty years ago people said the exact same thing about the computer. At the time, ProTools was just peeking around the corner (as an evolution of SoundTools), I think it could do maybe two or four tracks of audio recording/editing, and with terrible sound quality at that.
Professionals agreed, A computer is handy for certain audio editing tasks, but it's not going to replace a proper 48+ channel mixing console and multi-track recorder. It's just not gonna happen, Jim. Even when software and hardware became powerful enough to record and edit 16 tracks at the same time, the sound quality remained subpar and people invested in $100K editing stations because ProTools on a Mac just didn't have the professional sound quality for major label releases.
I'm sure you know what happened next. Nowadays ProTools is (if only just) the de facto standard in professional audio, multi-track tape recorders exist only in boutique analog recording studios catering to a niche market (and it is increasingly hard to find tape for those machines) and all the manufacturers of $100K digital audio workstations went out of business.
Computer audio sound quality improved, track count improved, and at some point in the early 2000's regular PC's (and Macs) became more powerful than the bespoke digital audio hardware.
The story today is remarkably similar. Audio pros all agree an iPad (or any tablet/mobile device) isn't gonna replace your MacPro or Windows workstation, the same way the computer was never going to replace a million dollars worth of the best audio hardware in the world.
In conclusion, I don't know whether Apple is moving away from the professional market, moving towards tomorrow's professional market, or whatever. I have absolutely no clue what that will look like ten or twenty years from now, nor whether or not Apple will be catering to it.
But like my sig line says:
"The world is ever-changing. Change along with it, or be a sourpuss."
