Logitech's new MX Master 4 wireless mouse, launching in October for $119.99, introduces a "Haptic Sense Panel" on its thumb rest. This panel vibrates to trigger customizable "Action Rings," offering shortcuts and app-specific commands. The mouse also features frosted buttons, a USB-C Bolt transmitter, and up to 70 days of battery life. While similar to its predecessor, the haptics offer a novel way to interact with software features and enhance productivity.
