27-inch iMac Also An External Monitor

"Today Apple released a new 27″ iMac with impressive specs, a unibody design and an impressive LED backlit display. Somewhat hidden in the announcement is a small but important feature - the DisplayPort connection on the back of the 27″ iMacs operates both as a jack for an external monitor and also as an input for an external computer if you want to use your 27″ iMac as a monitor."

I could have used this capability a year or so ago when my older iMac died. Some were noting that they were cancelling a 30-inch Dell monitor in favor of this since it "includes a free Mac." One way to look at it I guess!
