  Indeed. There are disadvantages. I guess what you're saying is that my Surface would charge more slowly on a pad than it will with its wire? So be it. I still want the convenience of wireless charging for my tablet/laptop. Here's the thing: my devices that charge wirelessly are in practice more often charged than those that require a wire. The speed of charging with a wire is immaterial if by requiring a wire, you have reduced the frequency of charging. And if it's about efficiency (cost) of charging, then fine, let me know it will use a bit more electricity. I'm still going to do it. I've got way bigger fish to fry there.

    Here efficiency is not only about costs but also about energy saving / protection or the environment.
