Ubuntu Edge
The Edge is trying to solve a problem in hardware which is best left to software.The problem: when you move between your devices, your apps look and act different, and they don't auto resume your state.  But that's just because the software isn't mature yet.  Eventually you will be able to compose a draft in Gmail online, unfinished, and the Gmail app on your smartphone will open to the draft automatically, and cloud apps will work the same everywhere--on the phone, on the desktop, and on the web.And even if the apps are not completely identical, they will be good enough: I can switch from driving my car to a rental car without any issue; the interfaces to a car are fundamentally similar across all cars.  So too with apps on various devices.  It's just not a big deal.  This is actually good for the Edge as most desktop displays do not support touch (and wouldn't work well if they did) so you'll still be shifting between touch and mouse, or touch and keyboard.Solving this problem in hardware is sub-optimal: you'll always be fiddling around with monitor, keyboard, and mouse cables; your CPU, GPU, and RAM is limited; and your Internet connection will be slower from the phone than it would be had you plugged in to your 100Mbps+ cable connection from your cheap Ubuntu or Mac desktop.
