So I'm going to be that dude...
Some of the UI changes are excellent, but not all of it is as great as the creator thinks. For example, the current app page has in-app purchases broken down. Jobs replaced it with a giant purchase button. How is that more useful? Now I have no idea how much the in-app purchases cost, or if there are in-app purchases. Would Jobs give each in-app purchase a giant buy-me button? That would look a bit silly. Maybe he could make in-app text smaller. Then you're right back to "can't please everyone," because someone would call him out for an inconsistent UI.
Jobs complains that the app icons are too big. Okay, then go into the display settings and change the scaling to better suit your needs.
He doesn't like the Spotify UI? Okay, email every third party dev and tell them to change their UI to his liking. That should work out well.
All apps MUST be transparent? That might be a reasonable request for Microsoft designed apps but that's not something devs should be forced to do.
Want to add icons to the Store's hamburger menu? Because I need more icons covering my screen.
And I can already design my Start screen to look like that. Add background image + adjust icon transparency + only use transparent icons. Ta-da!
Again, some of the changes ARE cool and pleasing to the eye. However, this feels more like a dude who took a few minutes to customize his start screen.
