I want to get an Apple 27" LED Cinema display at work. I already have a 13" 2012 MBA. And I want to use the display as my second monitor side by side. 1. Do you think i would need an extra keyboard + trackpad if I use MBA and the display side by side? 2. Apple released the currently available LED display in 2011. Do you think Apple will release a new series of displays next year? so that I can wait and get the latest one. 3. My MBA has MegSafe 2 power port. The LED Display comes with MegSafe 1 power cable. Will MegSafe1 to MegSafe2 adapter be shipped along with the monitor or should I get it separately (which is about $10)? 4. Can my MBA power such a large cinema display with huge resolution?
