I am thinking of getting the Surface 4 dock. From what I understand, I just need to attach the magnetic connector from the dock to the tablet and its good to go. That connector alone will take care of the charging while providing two monitor support plus 4 USB ports and the LAN port. I also have a Dell laptop with USB 3 ports. I know Dell has a laptop dock which when connected to the USB 3 port in laptop will provide extra monitor plus USB port support. Can I have similar functionality with the Surface 4 dock - by attaching one of its USB 3 ports to my laptop's USB 3 port?
