In my experience, it's slow to charge. I've been using the Magic Mouse for many years, because I otherwise like it. But charging it to last the rest of the day takes long enough that I lose track of whatever I was doing. And the low battery warning always comes so late that I must stop working immediately and plug in the cable.
It's probably just Apple's usual arrogance. They could have easily designed the mouse so that you can keep using it while it's charging, but the designer chose otherwise. And because this is a minor enough issue, Apple doesn't have to fix it and admit that they were wrong.
