From 9to5mac: "Heres something interesting weve found in the new 11 iMacs: The Keyboard System Pref contains the same option to illuminate the keyboard that MacBook Pros have. Previous iMacs as well as all other Macs without lit keyboards dont have this option. Many Macs without lit keyboards have ambient light sensors to know how bright the screen should be lit but those machines dont offer keyboard brightness settings. Could Apple be preparing or have delayed a wireless keyboard with backlighting? I can say with 100% certainty that Apple would have a winner if they released something like this, at least in my home. Bonus points if it has a built in trackpad On the other hand, Apple could have just made a rare mistake, perhaps copying one too many of kext settings from the Sandy Bridge MacBook Pros perhaps." I'd love one of these, depending on a decent battery life of course.
