It's really strange that Apple designs backlit keyboards to their laptops do not market to other brands because of the high prices and the need, it would bring a lot of money. It's really beautiful and thought the best apple keyboard without wire, its design does not swear to that of the Mac. The small negatives: the high price, the fact that it always connects Bluetooth even plugged in USB (only supported). Indeed, with a 27-inch iMac not updated (old OS), I never managed to connect but works great on mine with Mavericks.
