Creatives have always been a large target audience for mac hardware. Trust me, video editors and mograph people will always need more RAM. As long as people keep buying higher definition TVs and monitors. Hell, I've maxed out 128 gigs of RAM on a Xeon machine even when I wasn't working in 4k or 8k.
Mac's new laptop offerings cap at 16 gigs. There's a rumor about a 32 gig version, but even that is inadequate. Everyone on the design side of the office is still drinking the kool-aid and using their overpriced hardware because that is workable for their job, but on the video and animation side it's just not tenable. At all. All of us started on macs and switched to upgradeable hardware running windows or linux when it was revealed that apple just wasn't taking care of that demographic. There's a hard division down the middle of the room; macs on that side for photoshop and illustrator, PCs on this side for video editing, tracking, 3d effects, and rendering.
There's one exception: a mac pro "wastebasket" gathering dust in the corner of that office. That was a fucking slap in the face of a computer. All form and no function. Instantly obsolete. Not even remotely upgradeable. No resale value. And my god was it expensive. Jesus christ, you just can't rationalize that expense in good faith and of sound mind.
And I swear I'm not a mac hater. I grew up on them, have some great memories. But the math just doesn't add up anymore. They've become computer sculpture, not usable workstations.
I really don't think hardware will plateau. People have claimed since the eighties that new, vastly powerful computers are as much as the average user will ever need. Well, new uses are suddenly made possible which inevitably put that new potential to work, and gradually those applications become mainstream. If a new computer has fulfilled everyone's needs and more, it's only a matter of time before somebody finds a way to use that extra power for the average person.
It's happened before and it will happen again. In the coming years we're going to marvel at all the useful things we can do with terabytes of cheap RAM on a consumer PC, and we are going to wonder how people in the olden days got by with only gigabytes. Just like we do with the days of megabyte-scale RAM. It will happen.
