If you do not have one, buy a dock! I have a sp6 and 4 , and having the dock makes it quite the device. Speakers, multiple external monitors, keyboard, mouse -- a full desktop setup, I can grab and either stick a keyboard cover on or just use as a reading device on the couch.

Back to work? Sit on table, one cable and it's back to a desktop and charging up again.

Makes the whole thing make far more sense.
