But for them to carry around.

Effectively they want an universal docking-station for smartphones, I guess.

Microsoft sort of had this with Continuum. It was great and hardly anyone used it. Previously Motorola had the "lapdock", too.

Hardly anyone used it because it was barely available on a single brick of a "phone" from HP, with a price only a corporation would consider.

As for the motorola attempt, it needed two plugs (hdmi and USB), and they could never commit to having a single spacing and overall phone shape across generations. End result, each phone needed its own docks until Motorola went "fuck this" and released a lapdock with some massive cables instead of the dock plugs.

And the Samsung attempt seems poised to develop the same problem...
