>I want to use my mouse full time while plugged in due to poor reliability when unplugged, and only Apple's devices say no--for reasons that don't make sense.

The reliability would not be affected since it moves data wirelessly. The data will never go over the charging cable so your reasons for keeping it plugged in don't make sense.

If I turn off bluetooth and plug my "wireless" Apple keyboard into USB, it works fine, sending data over USB. There's no reason why they couldn't make the mouse the same way.
