Apple unveiled the new iMacs on its Web site Tuesday. The machines feature quad-core Intel Sandy bridge processors, FaceTime HD cameras and Thunderbolt input/output ports.
The new iMacs start at $1,199 for a 21.5-inch model with a 2.5GHz i5 Intel processor and a 500 GB hard drive with an AMD Radeon HD 6750M graphics processor, and $300 more will get you the 21.5-inch model with a 1 TB hard drive with at an AMD Radeon HD 6770M processor.
There are also two 27-inch models: a $1,699 1TB hard drive with a AMD Radeon HD 6770M and a $1,999 1TB hard drive model with a AMD Radeon HD 6970M.
Upgrading to the speedier i7 processor costs $200, and those who want a lot of space can get a 2TB hard drive for $750.
The new camera supports high-definition calls between all FaceTime HD-enabled Macs, plus standard-def calls with other Macs and the iPad 2, iPhone 4 and current iPod Touch.
In addition to one Thunderbolt port on the smaller iMac and two on the larger one, the computers also sport four USB ports and a FireWire port.
