According to Microsoft’s ‘roadmap’ for Windows 10 , the Continuum-powered laptop is basically an empty tablets with a screen, powered by a phone that slotted into the back of the tablet when needed.
This is what Microsoft said that the laptop will not have any CPU or OS. When paired with a Continuum-compatible phone, it will allow you to use your phone like a laptop.”
It is not clear if Redmond will build it, or if it is just a design standard for Windows Phone 10 manufacturers will be able to use. It would appear that the laptop will still have a drive and all the other gibbons, but will look to the phone to be the processor. We guess it will also be able to swap data between the two devices.
