21.5" Thunderbolt iMac can do Target Display Mode with other Thunderbolt Macs - pinkoos - 10-31-2011
I always thought that the Target Display Mode was only reserved for the 24"/27" iMacs. Apparently, the new Thunderbolt 21.5" iMacs can serve as a monitor for your Mac as long as your Mac is a Thunderbolt Mac.

"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.
However, this feature doesn’t work with older Macs that have only a Mini DisplayPort connector. Apple does not appear to be providing adapters to accommodate this capability, and there’s no news from third parties of compatible adapters either."

AFAIK The 24" iMac didn't support target display mode.

Okay, my mistake. Looks like it is 27" only for pre-Thunderbolt iMacs and 21.5" and 27" for Thunderbolt iMacs.
Thanks for pointing that out.
