Computing power has been upped as well, now starting with a 3.06GHz Intel Core 2 Duo processor, and going up to a quad-core Intel Core i5 or Core i7 “Nehalem” processor in the 27-inch iMac.
You can pack it out with up to 16GB of RAM and up to a 2TB hard drive, and top out the graphics spec on the 27in iMac with an ATI Radeon HD 4850 graphics processor with 512MB of GDDR3 memory. That should be enough to take care of even the most animated of shape-throwing sessions.
On the peripherals scene it comes with the familiar wireless keyboard and the brand new Magic Mouse for a touch of, er, Multi-Touch fun.
Apple is keen to tout its eco credentials, and apparently the new iMac meets Energy Star 5.0 and EPEAT Gold requirements, meaning it should be lighter on the 'leccy as well as having used fewer harmful substances in its manufacture and easier to recycle at the end of its life.
Prices start at £949 for the 21.5in and £1349 for the 27-incher.
