Apple's super-slim iMac 2012 priced from $1,299

Apple has priced up its beautiful new iMac all-in-one desktop, with the achingly skinny computer priced from $1,299. The 21.5-inch iMac kicks off at $1,299, with a 2.7GHz quadcore Core i5 processor from Intel, paired with 8GB of RAM and a 1TB hard-drive. There's also GeForce GT 640M graphics. Of course, Apple also has a bigger model too.

The 27-inch iMac is priced from $1,799. It has a 2.9GHz quadcore Core i5 processor from Intel, paired with 8GB of RAM and, again, a 1TB hard-drive. It too uses NVIDIA graphics, in the shape of the GeForce GTX 660M GPU.

Both can be specified with considerably higher kit, however. There's the option of up to 768GB of flash storage or either a 1TB or 3TB traditional hard-drive. However, there's also Apple Fusion Drive, which combines both flash and hard-drive storage in a hybrid, for the speed advantages of an SSD and the capacity of an SSD.

The new iMac will be delivered with a wireless keyboard and either a Magic Trackpad or a Magic Mouse. An external optical drive will also be offered. The 21.5-inch model will ship in November, while the 27-inch version will ship the following month, in December.
