Can't believe I didn't know about these two great Logitech devices until now. Anyone with multiple computers knows how annoying it is to switch keyboards/mouse. Either you clutter your workspace with multiple keyboards and mice or you need to pair/repair every time you switch computer. The K780 keyboard and the M720 mouse solves this. Connect up to 3 devices then select which one you want to use. Switching to another device is easy, just a press of the selector key/button.
The keyboard itself is very stylish, with these round keys instead of the more traditional square/rectangular keys. Key strokes are smooth and not noisy. My only complain is the built in tablet stand (white piece in the photo) that cannot be removed. As for the mouse, it's full size and very comfortable.
Both are pricey but you get great multi-device support and don't need to buy extra keyboards and mice. Great job Logitech!
