Besides the large work surface, the trackpad lets you control your Mac with gestures like on an iPad. People who are used to this tablet will feel at home. You can zoom in with a wave, select the text, return to the previous or next page in Safari, change or display location, display all the tabs in your browser, view all open windows, display notifications, ... Learning is very fast even for a senior. Everything is very well explained through a video showing the actions in the system preferences.
The trackpad works on batteries unlike Logitech product. Nothing to install, everything works as soon as the device is connected to your machine.
If you hesitate, know that you will not try more than you spend. There remains the question of the price which is important when a good mouse costs only 20. Still, it is not at all the same use, gestures allow you to work faster and more efficiently.
