I thought about how I use my SP3 and quickly realized, wireless charging--where I would need to lay the device flat on a charging pad--would be an inconvenience for me. I don't think I would ever use it. When I'm using the SP3, it is on the kickstand or in my lap. When I'm not using it (When am I ever not using it?) it is in my bag or backpack. At home and at the office it is on power all the time, so I normally just leave it up on the kickstand, with the power in. When I take a sleep cycle, I just close the key cover and leave the SP3 standing.
If I mostly used it in meetings or class, I could see how it would be convenient to leave it laying on a charging pad and grab it when needed for note taking. That is just not how I use mine.
