With the charging port on the bottom of the mouse, it means that you can’t use the Magic Mouse 2 while it’s plugged in. People have been outraged by this design decision–those same outraged people also don’t have the full story about the Magic Mouse 2 or has never used it. Apple has said that the Magic Mouse 2 (along with the Magic Trackpad 2 and the Magic Keyboard) are fast-charging devices; the mouse can get nine hours’ worth of battery life in about two minutes. So, in the time it takes for you to visit the bathroom, stand up because your Apple Watch told you to, or go to the kitchen to grab a beverage, your drained Magic Mouse 2 will have a charge that will last a typical working day. Really, the charging port on the bottom of the mouse isn’t a problem — but sometimes people need any excuse to be outraged over Apple products. “
Roman Loyola is spot on. I think any complaints about the location of this port are misguided; people are just looking at things to criticize. They’d do better to criticize the prices of Apple’s new keyboard, mouse, and trackpad.
