yes, some of the models are already up for sale. (not the high end ones, they ship in november). the imac 24" from early 2009 is not on the list of unsupported devices for the 30" ACD either though, so I am asking:
does anyone have a picture of an early 2009 iMac (or a new late 2009 iMac) being used with a 30" Apple Cinema Display?
Or get the Dell 3008WFP and a mDP-DP cable from Monoprice or Circuit Assembly if you really don't feel like waiting forever. It's also the cheapest option.
