Well, that was quick. 

Immediately following a rumor that new iMacs were on schedule to be released this week, Apple quietly rolled out upgraded versions of its popular all-in-one machine. 

The upgrades are modest and happen all underneath the aluminum body. The iMacs get treated to Intel's latest quad-core Core i5 and Core i7 processors, and now sport the new high-speed Thunderbolt data ports. There are also faster graphics cards and an integrated FaceTime HD video camera. 

Prices for the new machines start at $1,199 for the 21.5-inch, 2.5 GHz quad-core Intel Core i5 model with 4 GB of ram, 500 GB hard drive, and an AMD Radeon HD 6750M graphics card; all the way to $1,999 for the 27-inch, 3.1 GHz quad-core Intel Core i5 model. 

All models are available now from the Apple Store.
