Re: Nothing new..
Wouldn't it be less faff to just stick an ARM SoC into the 'docking' hardware?
If you've gotta carry a dock (and mouse and keyboard, unless you find them at your destination), you might as well carry a discrete headless computer. It could act as a wireless router for your phone, throwing up a local VPN between itself and your phone for the purposes of syncing files etc, and bridge it to the wider net. Or summat.
Or maybe it's just me.
