I am considering purchasing a MBA for my wife and would like to have it periodically hooked up to my monitor/kb/mouse setup for my Mac Pro. My fp allows multiple VGA inputs. Can I cofigure a wireless kb and mouse to two computers? So when the mac pro is on then it syncs to it...turn it off, connect the MBA to the monitor and it syncs to the kb and mouse. Will this work as to avoid a KVM switch? Are ther any better set ups that would also power the MBA? Basically I need a cinema display with dual inputs.
