This is honestly the more interesting answer. Having a little device with a portable screen, keyboard and mouse that you can attach to various RPI as needed. As for price how about a nexdock that has a port where you can stick a Pi Zero in or even just include a Pi Zero, I would be happy to pay $5 more for it?

Scratch that: Motorola Lapdock 100 is the same thing as this laptop http://hackaday.com/2016/01/26/turning-a-lapdock-into-a-lapt...

Edit: Just wanted to call out this line from the above article.

> The Lapdock 100 has long been a useful accessory for the Raspberry Pi

The market has a problem and this was a solution. The phone /laptop isn't really a problem that people need solving. But the Pi owners have a problem they need solved.

Just imaging a Pi with a USB-C port connected to one of these laptops via just 1 wire.
