Ubuntu especially are now focusing on blingy desktops that somehow require really new cards and hardware only, and yet are also trying to throw away the traditional desktop to cram themselves onto a phone. And yet with high end requirements they are now not the desktop OS of the light weight / poor hardware people, they are for the high end only paradoxically.
Android is coming the other way: a good core set of features now slowly building out into a potential desktop replacement. Because the desktop is still important, especially for anyone looking to do any productivity work.
And after watching a fast demo on the site, I see another thing Android is doing right. Somehow even though it's incredibly low resource it has animated desktops. I was first exposed to the idea in the mid 2000s with a video demoing Enlightenment 17 showing animated desktops. I even made a bug with Gnome asking for the feature. No dice. Even with all their modern "bling" and high and hardware requirements, they can't do live wallpapers/desktops. So with a lame static desktop, try running them on this hardware? EXPLDOE. Won't work.
Meanwhile light little android also has this cute feature.
And this really just underscores to me that in all ways Ubuntu/Unity/Gnome shell are just going in all the wrong directions while Android seems to be increasingly going in many of the right ones.
