I wish the Motorola Atrix concept of plugging your phone into a laptop-shell and using the phone's CPU, memory, storage, etc. had taken off. My iPhone is already much more powerful than this ARM laptop, but I obviously can't use it like a laptop.

Would be nice if there was a standard so, any USB c phone could plug into a display - along with the display acting as a hub, and/or Bluetooth for keyboard.
[ed: for desktop/dock. See sibling for sentio - which is for turning phone into laptop]
In android world, the concept is alive & well. I myself use the sentio desktop app to connect to a monitor and use a bluetooth keyboard/mouse.
