Apple refreshes iMac line with faster CPUs, Thunderbolt ports | Crave - CNET: Apple announced updated iMac all-in-one desktops this morning, adding Intel's second-generation quad-core Core i5 and Core i7 CPUs and Thunderbolt data ports. The new models are available for purchase immediately from Apple's Web site and its retail stores, with prices ranging from $1,199 for the 21.5-inch iMac, and scaling up to $1,999 for the 27-inch model.
Aside from the updated CPUs and the new high-speed data port, the new iMacs sport faster AMD graphics than their predecessors and integrated Facetime HD video cameras. Otherwise, little else about the iMac has changed from the previous models that debuted in June of 2010 (that includes external design--the 2011 and 2010 models look all but identical).
