Two additional chargers, one that stays in my backpack and one for the other room in my house where I work: $180. $150-ish worth of dock for my desk so various stuff works including Logitech wireless mouse, monitor, external drives -- I didn't choose one yet but that's the price range. DVI for projectors and HDMI for various stuff: $100. Three $10 usb-A dongles, one each of which would probably be tied to the power adapters because I personally and professionally have a dozen devices that use usb-A. And the above is well over $400.
