Logitech’s K780 Multi-Device Wireless Keyboard is expected to be compatible with devices of all types i.e. mobile, tablet and PC. Not only that, it is even compatible with iOS, Android, Chrome OS, Windows and Mac OS as well. The device provides an effortless interchanging between the tablet, PC, and phone. The Logitech keyboard has a number pad and complete set of functions keys. The specific keys will automatically change function depending on the operating system it is connected to for instance ctrl will change the function to command while changed from Windows to Mac OS. The rubberized tray running along the device length can hold the mobile device in an angle that is comfortable to view.
The K780 has the ability to connect to three devices at a time via Bluetooth. In addition, the devices without the Bluetooth connectivity can be connected via the Logitech Unifying receiver. The white buttons at the top left corner can be used to activate the devices connected to the corresponding button. The round concave keys not only look different aesthetically from other keyboards but also gives a typewriter like feeling.
Well, the real purpose of the keyboard is to allow the users type using other fingers rather than only the thumb at which it is excellent. The keyboard weighs at 1.9 pounds (875 grams) and is not very portable.
