Only thing that is missing is a wireless charging. Some competitors use Qi charging or a special mousepad, so there's never a need to plug it in.
In 2010, Logitech released a solar-powered keyboard called the K750. Now that batteries and PV cells are improving, and low energy wireless technology is improving, I bet this would be less terrible.
Also in 2010, RCA invented an "Airenergy" device that could harvest ambient wifi signals for use as a power source.
I imagine some combination of the above technologies could eliminate cables from peripherals entirely.
The Qi mousepad makes a lot more sense.
Is that new? When I was originally playing with dd-wrt I was under the impression that 100 was the limit, discovered my AP was defaulting to something like 70mW, and would allow you to go higher.
Makes no goddamned sense to me.
I love my original MX Master, but it really annoys me when I have to deal with that charging cable. USB-C might be a marginal improvement, but I' love to be able to just put the mouse on my Qi pad when I leave the office...

I have those on my wireless mice/keyboards, and game controllers.

They managed to improve an already near-perfect mouse. I just love the 3. Probably not worth ditching your 2S for, but nonetheless, a superb upgrade. I always felt the thumb buttons were awkward on the 2S and that has been rectified. The magnetic wheel is also really nice to use.
