It is all great if you do not have existing hardware you want to use. I have a Logitech mouse I love, it has a USB connector receiver that sticks 3 mm out of my laptop so I keep it plugged in all the time. The idea of it hanging of some cable adapter is just silly, not even mentioning the fact that you have to buy it. Or my fancy 27" Apple Thunderbolt display. I had no issue paying the Apple tax because I loved the display and it doubles as a docking station (integrated power adapter). Guess what, it doesn't work with the new laptop. The new display they are selling is made by LG and was not available for purchase until few weeks ago.
