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."
