Previous-generation iMacs were able to drive both the internal and an external display at the same time, but the newly released iMacs are capable of driving two external displays simultaneously – in addition to the built-in display – thanks to the inclusion of Thunderbolt ports. Apple confirmed to GigaOM’s Darrell Etherington that the new 27-inchers’ two Thunderbolt ports (21.5-inch models only have one) can drive a dual external display setup.

Macrumors was able to verify that the Thunderbolt ports can still make the iMac an external display for Blu-ray or video gaming or a cable box.

 

Engadget tested out a dual external monitor setup, seen below.

Apple also offers touchpad options allowing you to replace the included MagicMouse with either a Magic Trackpad or a wired Apple Mouse or go with both wireless MagicMouse and Magic Trackpad for $69 extra.

Also, MacStories explain that you can order a solid state drive in the second drive bay that will boot your operating system.

(we’re doubting Apple is supporting symbolic links to the hard drive for media – but maybe in Lion?)

MacRumors also notes that Boot Camp upgrade is available for new iMacs that also addresses issues with Japanese and Korean keyboards on early 2011 iMac.
