If you play with a Sony DualSense controller or Meta Quest 3, you're probably very familiar with haptic feedback by now. It is practically unheard of for mouse and keyboard players, though, yet recent leaks suggest Logitech could be employing the rumbly tech.
According to Winfuture, the new Logitech MX Master 4 has haptic feedback "to provide feedback on actions such as changing computers, adjusting the cursor, and similar actions". It seems that, instead of being used to heighten immersion in games, it has a much plainer, but likely more productive, use.
