Abridged version of the video:
•Dark Mode: We had that in the 90's in Mac OS 8. It was called Kaleidoscope, and it could do more.
•Stacks: Worthless is you have multiple formats/dates/ect. of files that all have to do with the same project. That's what we have folders for.
•Gallery View: It already exists. it's called Bridge, thumbnails, and coverflow.
•Quick Actions: Not really handy for real projects. Just rotating the image in preview mode doesn't really do anything turning your head doesn't already do. (Insert Anakin saying "I'll try spinning, that's a good trick." joke here)
•Screenshot: Nothing new here. We already have all these features. They just redecorated existing functions.
•Desktop iOS apps: Programs you didn't want or use, stuffed into your hard drive, taking up valuable space you can't afford to squander. Especially considering how much Apple reams you on the cost of a drive. And here I thought Windows was the OS that had the bloatware.
•New App Store: Oh goodie. They made a new way for you to give them your money.
Summation: They really had no new ideas this round. Really disappointing.
I don't see how having the first point is relevant, unless you use Macs from the 90's. I want that dark mode on my current Macs. And also, you're ignoring the part where it just looks ****ing beautiful.
As for the App Store, you're looking at it completely wrong. Developers have been asking for Mac App Store improvements ever since.... Mac App Store. The App Store is a way to get your app discovered, a way to distribute your app and a way for you to earn money as a developer - so that you actually get to make more apps. Want good apps on the Mac? This is one of the ways to do it. Not to mention they allow apps to access more of your Mac in a secure way, which is what brought BBEdit back. It's big. Finally, you missed the whole UIKit on Mac thing, which also has the potential to be huge.
As for the rest - talk about negativity. These are some genuine nice things. Nothing groundbreaking, but nice.
You should've summed your whole post into: I didn't like it.
