I don't think that is really the point. The point is that it can store the settings for 3x devices and you can switch between each one of them individually as needed.

For example, if you had an iPad and iPhone you can have them both configured as the 1 and 2 positions, and switch the switch as the relevant device was docked.

With a lot of existing Bluetooth keyboards you would need to re-sync it each and every time you switched devices.

First thing I thought was that having both my PC and my Mac Mini on the same keyboard would be cool (and this is a fair bit cleaner than a KVM)

Check out http://synergy-project.org/ you can share your keyboard and mouse between the computers. Just move your mouse to a screen edge and it jumps over to the other computer.

I use it for work, OSX on my left Windows on my right, single keyboard and mouse. It will even let you copy-paste text between computers.
