I was pretty disappointed that all mouse/keyboard desktop UIs stopped evolving in the early 2000s--especially as they all transitioned to hardware-accelerated desktops. I stuck with macOS because the laptop hardware was a lot more solid, I like Unix terminal, sleep/wake and battery life was way better, and a few other more minor things, but as for basic productivity of the UI; all three platforms are basically the same. I think there's still a lot of potential in alternative desktop interfaces, but that ship has sailed long ago. Tiling window managers have found a niche. I really like the idea of the Hotbox from Maya (3d software), but the only other place I've seen it used is Autodesk's Sketchbook. I'm very glad Apple is trying to come up with something else, even if they settle back on traditional desktop interactions. However, I think they're too big and entrenched to be too adventurous.
