Very nice keyboard. The function to switch computers isn't something that you see too often, and works very well. I carry this to work with my laptop and I use is on my desktop at work and I use it when I go home at my desktop there. I always have my laptop with so I'm able to use one keyboard whether I'm at home or at work. That being said I charge it maybe twice a month.
It's very convenient to switch between PC's without having to use the windows interface, or turn off the bluetooth radio on one device so it doesn't connect to the wrong device, with this all you have to do is press a button wait a couple seconds and start typing.
