Yeah, that's what you need on a desktop. A OS designed for "touch" with "innovative features" (which features were standard on a desktop 25 years ago).
Years ago I installed a mouse driver for iOS on a jailbroken iPad 2 on iOS 6, it more or less worked for most applications that didn't require two finger gestures. I was able to paint with Brushes and such.
It wasn't a pleasant experience but I was just tinkering to see what it'd be like. If you like big huge icons, zooming when highlighting, and having to occasionally touch your screen, I suppose it was good.
I can't imagine its about being a viable desktop OS more than push the envelope of Android.
The UI looks like a uglier clone of ChromeOS.
