Does a portable screen/keyboard dock for a mobile exist?

I'm imagining something that you slot your phone into and you have a laptop.

Does it exist?

Sorry, specifically want do something to turn it into a laptop not desktop.

Get a laptop ......

...haha I like the idea of having just one device

My problem is that fact you still have to carry the phone and.....phone laptop!

Might as well buy a real laptop!

Yeah, if I was looking to move about with the device then yeah you might aswell get a laptop...however this is just a device for at home (I don't have space of a desktop) and I thought that it would be nice if I just bought a top of the range phone every couple of years rather than two devices.

Currently I have the One+5T which is actually probably faster than the Toshiba Chromebook I use!
