Microsoft is continuing its efforts to play nice with non-Microsoft branded devices. Their latest offering, the Microsoft Universal Foldable Keyboard ($99 USD), is a prime example of this. Perfect as a travel companion wherever you go, the ultra-thin, lightweight keyboard works with your tablet or smartphone. It will even pair simultaneously with any of your two mobile devices — iPad, iPhone, Android devices, Windows tablets, and of course, Windows Phone. With a single touch the keyboard will switch to whatever device you’re working with. When you’re done you simply fold it up, shut it off and stow it away.
