I haven't used Windows 10 much. After installing it back then, I played around with it for a while to get an idea of the changes since Windows 7 (I skipped 8). A few weeks later, I spent an hour or so configuring and customizing the system so it's ready for work, should I need it at some point.
Both times, I couldn't help but be excited at how goddamn fast W10 is. A few days ago, I played around with it, again. And it really is fast. There are no UI slowdowns or lag. Everything's instant. None of the built-in apps has any noticeable loading times. Click it, the window pops up, the content is displayed. Instantly. Even the browser, Edge, is just incredibly fast.
I wish OS X would come just remotely close to Windows' snappiness. But it doesn't. When I click the apps folder in my Dock, I can count the frames of the opening animation (it's set to 'Grid'). Well, no, that's hyperbole, but seriously, I almost can count them. It's even worse when I scroll in that app grid. "Scrolling". It's so laggy, it's more like flipping through pages.
How about the animation when opening new windows? Open Safari, hit cmd+N ten times in a row and get some coffee while you wait for the windows to appear one after another. Oh, and with that many windows open, the frame rate of the animation when activating Mission Control is so bad, it's actually almost like there is no animation at all. It just goes *pop* and the view switches.
Switching spaces? It still gets stuck all the time.
Safari either crashes or freezes at least twice a week. Or slows down to a crawl while I'm typing into a simple textfield while 1) no other tabs or windows are open and 2) no resource-intensive apps are running. I'm speaking of this very Post Reply field on GAF I'm typing in right now.
Why does shutting down my Mac take several minutes? Yes, I already reset the PRAM and the SMC and did all the other shit everyone recommends for every single kind of problem but which never actually fixes anything.
Don't even get me started on reliability. iCloud, Back to my Mac, Continuity, Apple Music, iTunes Sync, System Updates. Shit's broken. "It just works"? Piss off.
Two weeks until El Capitan. Allegedly, UI performance is indeed improved, but still not on Windows levels. Acceptable levels. Granted, I was told this from a beta user quite some time ago, so it might have improved further in the GM. Don't know. Let's see.
