While I agree that Mac trackpads are fantastic, there's still a need for variety. For some reason, I don't feel at home using a trackpad in certain programs, such as Photoshop. The Magic Mouse feels better in that scenario, like I have a little more control.

For general computer use and coding, I prefer the trackpad.

Sometimes I'm using it as a laptop, the touchpad is absolutely great, I wouldn't do it any other way.

Other times, I have it plugged into a monitor and a desktop keyboard. In those cases, I want a real mouse plugged in.

Because mouse has more buttons and can use better gestures and rocking clicks to go back and forth

I generally prefer the trackpad for productive tasks, but I never got the hang of using it for my weird Minesweeper obsession. A mouse has a lot of non-input leverage and physical control that’s very hard to replicate (for me, others swear by trackpads even for high pace, high accuracy pointer input like this).
