 The Best Bluetooth Keyboard! It needs to be said: This keyboard looks great. It walks the Apple line of being extremely clean and minimal while its aluminum construction makes it feel beastly strong. It works just fine with OSX Macs, Windows PCs, iOS devices and even Android tablets and phones (though, obviously, it works better with the Mac stuff). 

 Ooh, keyboards. Exciting, right?! Oh, are you nonplussed? Get over it dude: The concept is of a single keyboard that works really well across all of your computers, tablets, and even your phones is actually something incredibly appealing.
