Logitech K810 - one keyboard for phone, tablet and computer

I love this idea, but more for the fact that I could pair both my laptops to this one keyboard and switch between them without having to plug/unplug anything. It's a keyboard that can be paired with up to three devices, including computers, tablets and phones, and hot swapped between them.
