I'm seriously considering the 11-inch MBA for purchase as a semi-replacement to my aging white 24" G5/Intel iMac. I'm curious to know if it's even possible to mirror display to it from the MBA? Hopefully, I'm not S.O.L. as it seems the display ports for either machine don't look identical. The MBA would be my 1st 
laptop computer and I'd like to avoid buying the separate display for the few times I'll need it for doing things in iPhoto, iMovie, etc.
