I had the M600 hopeful ordered that it at least comes close to the Magic Mouse. But no, the mouse looks cheap and compared to the Magic Mouse is included Software a Witz the only option is to swap the two mouse buttons. Since the Magic Mouse also costs the same, I can only return the M600. The Touch concept in conjunction with a mouse provides a lot Möglichkeiten- Logitech seems to have only brought a touch mouse on the market because the competitors do it. Too bad.
