All the new bumps in speed and LED screens is awesome but this new feature is a bit of a game changer and something that’s been lacking for some time now (from Macworld):

“In a clever touch, the 27-inch iMac has a new feature that dramatically increases its versatility. Via a series of adapters Apple says will be available shortly, users will be able to attach external display sources, such a DVD players or even other computers, to the iMac’s display. At that point, those sources will take over the iMac’s display, effectively turning it into an external monitor or an HDTV.”

I used to use my Dell 20” monitor as an HD screen for my XBOX 360, Cable and Mac and it’s this versatility that means I’ve held onto it after 5 years when I could have easily replaced my setup with an iMac but I didn’t becuase of this feature. Makes this a lot more viable next time I get that upgrade itch. Nice one Apple.
