Seems about every 2-3 years a company tries this. And every single time my hopes go up like crazy. I SOOOOOOOO want this. and every time I'm disappointed. The ipad pro is close, as is the surface book.
What ends up biting me is the need for a docking station or a laptop form factor thing for use on the go. If display glasses/goggles could ever become usable for long duration it would go a long way towards making a single device usable everywhere.
I think Bluetooth and Miracast are getting us very close to a good "on the go" solution. Even without things like hotel screens picking up Miracast support directly yet, the price of a good Miracast supporting HDMI stick has dropped spectacularly (Amazon's Fire Stick, Microsoft has a Miracast-only "stick" I forget what it is called). Between that stick and a good Bluetooth keyboard/mouse combo you have most of an on-the-go solution.
