The Logitechs MX Keys mini is a small, platform-agnostic wireless keyboard. It lacks the numpad on the standard MX Keys. The keyboard costs $99.99, even though it is smaller. However, there may be enough extras to make this keyboard the better option (if $100 is possible).
Logitech has added an emoji key to its top row of Minis function key. This allows you to add personality to your messages. It also includes a voice dictation key, and a mic mutes key that mutes at a system-level, not per app. They are joined by media and volume keys on the function row, as well as an option to adjust keyboard backlighting.
The MX Keys Mini can charge via USB-C. It can also flip between three Bluetooth devices using keys that allow you to switch. This model doesn't come with Logitechs unifying USB receiver and won't work with any one you may already own. This Bluetooth-only device is compatible with Logitech's Bolt USB receiver, which lowers latency while adding more security.
The MX Keys Mini has many other features that are similar to the MX Keys. The keys are concave and matte-textured, which makes it a great keyboard. Backlighting is also available. It turns on automatically when your fingers touch the keyboard.
The default MX Keys Mini version shows both Windows commands and macOS commands. It is also compatible with Chrome OS and Linux. There are three colors available: graphite, pale gray and rose. Logitech also offers a version for Apple products and macOS users who prefer not to have alt and start buttons. The same price as the desktop keyboard, but in a pale grey colorway that resembles Apple's older desktop keyboards.
Logitech claims the MXKeys Mini can last up to 10 days with the backlighting on. It can, however, last for up to five years with the backlighting off.
A decent wireless keyboard with scissor switch is not necessary to cost $99.99. The MX Keys Mini's price might not be as high if you have multiple devices, especially if your mouse is the MX Master and Anywhere. Logitech's Flow feature allows you to move files between Windows and macOS PCs when used with one of these.
