In all the excitement over the brand new iMacs announced this morning, it seemed as though one feature of the older modelsTarget Display Modehad fallen by the wayside.



From PCWorld:

Apple has confirmed to Macworld that the new iMacs can be used as external displays via their Thunderbolt ports. However, to do so, you'll need a Thunderbolt-equipped Mac, such as one of the early 2011 models of MacBook Pros. Connecting the MacBook Pro to either the 21.5-inch or 27-inch Thunderbolt-equipped iMac will let you use the desktop as a display for the notebook.
