Finally, we will have the ability (once the rest of the line is refreshed) to drive any display we want from any Mac. Finally we will be limited to the actual capabilities of the GPU and not by the connector available.
Specifically, I'm quite excited that the MacBooks can now drive displays requiring dual-link DVI (30" ACD, for example). Even the old GMA950 was capable of driving such a display...but the lack of the appropriate dual-link connector meant we weren't allowed to.
Probably the biggest deal will be that (I assume) the iMac's will have this new mini displayport once they are refreshed. Coupling a 24" iMac with a 30" ACD will now be possible. A non-Mac Pro, decent dual head setup will now be possible.
