MagSafe was in the sweet spot IMO. Doesn't require too much alignment, symmetrical pinout, disconnects quickly and safely, low mechanical wear from use.
I've taken to buying magnetic USB cables for this reason. Plug a connector into the bottom of phone/tablet, put a cable at work, in car, and next to the bed, and it's super easy to connect and disconnect, with no worry that the Micro-B connection is getting bent (with cats and a child we've gone through way more USB Micro-B cables than I would have expected).
I can see one significant improvement for the wireless mats. The number one part of my phone to fail first has always been the charging port. The mat reduced the wear and tear on that port which could extend the life of my phone.
Cables were never old, painful nor requires thought. I see the cable, I plug.
Your side is just that, an opinion.
