4 Logitech K480.
Logitech has unveiled the Logitech Bluetooth Multi-Device Keyboard K480, the first desk keyboard designed for use with up to three devices, regardless of computing platform. Now you can type a report on your computer and, with the flick of the Easy-Switch dial, respond to a message on your smartphone and type a tweet on your tablet. The universal keyboard can connect to three different Bluetooth wireless devices at once, whether you are using a Windows, Mac or Chrome OS computer, or an Android or iOS tablet or smartphone. You can type in comfort on a full-size desk keyboard with a familiar layout and all the shortcut keys you use the most. The durable, integrated stand firmly holds your phone or tablet at just the right angle for you to read while you type.
