Apple have launched a new iMac with 20 to 24 inch screen and nothing smaller that that. Big is better we all know that or at least that is what they are trying to tell us. It is $300 dollar cheaper and has a new aluminum cover instead of the old plastic once. It is of course much faster then the old iMac and Apple believe it is going to be a best seller. When you consider that the iPhones and iPhods are just flying of the shelves you can assume people want something to back it all up on and what is better then a new 24 inc iMac? If you want the total specification for this baby you can check use this link for iMac.
