But then you might have something urgent to do and cannot stop using the mouse. Then...you forget about recharging. Rinse and repeat, until you get at 0%. I know it's not a big deal but it would not have been a big deal either allowing the mouse to work and recharge via USB at the same time by not putting the port beneath it.
While I admit that it seems rare/odd, I can imagine trying to look up an address, catch a bus, and my mouse dies.
10 seconds becomes minutes, and bus missed.
I think the point here is, it could have been designed like thousands of other mice on the market, was not, and Apple is supposed to be about usability.
Hand waving "but you could do this", doesn't change the fact that you're having to do this, instead of using your mouse.
Perhaps this is what Think Different means? You're using it wrong?
The main issue with the mouse is everything else. It is uncomfortable to hold, painful to move around, awkward to click and do the gestures. The sensor is worse than a generic $10 mouse you can get off Amazon. It misses the first couple of clicks every morning.
Horrible, horrible mouse. But not because of the charging port, that's ok.
