I love the magic mouse.
I’ve used it almost exclusively as a mouse for over a decade. Though I love Apple’s trackpads, and also use them whenever I’m as part of the MacBook away from my desk, at my desk I can’t seem to get Apple’s Magic Trackpad (or any other mouse) to work for me.
Perhaps it’s the ergonomics of trackpad and keyboard together, or maybe I’m just used to the tiny Magic Mouse; but either way I love it.
Between the gestures and tiny movements of the mouse (I set the speed to as fast as it can go) I feel a level of precision and control that can’t be replicated with any other device.
Also, I hate plugging it in, but it’s a minor convenience every month or so that I put up with.
