QUESTION
Should I buy a used Apple Magic Trackpad or Logitech MX Anywhere 3S?
Buy the used Apple Magic Trackpad if you mainly use a Mac or iPad and care about gestures, scrolling, Mission Control/App Exposé-style navigation, or a laptop-like feel. Buy the Logitech MX Anywhere 3S if you want a compact, precise mouse that works well across desks, travel, and non-Apple setups.
My pick for most Apple-device users: used Apple Magic Trackpad, assuming the condition and battery are good. It gives you the macOS/iPadOS gesture experience that a mouse can’t fully replace. If you do lots of spreadsheet, CAD, gaming, or click-and-drag precision work, choose the MX Anywhere 3S instead.
