Few questions: 1) Is there any way to use this display on a PC (alienware) with a display port connection? Would the camera on top work? speakers? 2) If I buy the older cinema 27 with display port, what am I missing? I have a macbook air display port, but Im wonderng what I'd be missing compared to the new display with thunderbolt? 3) Also, am I reading this right, or does the Mac Pro NOT work with either of these? 4) I see the older model on Amazon for the same price..no discount. Is there a better place to buy the display port version? Or is there an adapter for the thunder version?
