While we here in Brazil, we hope that Apple will fulfill its promise to deliver the new iMacs in December, outside there is already talking about the availability of the high-end models, announced along with all the others in late October.

According to Electronist, Apple started this morning to notify customers about shipping iMacs with Intel Core i5 chips, indicating that the first models are likely to arrive at their destinations probably by the end of this week.
The difference between the busier Core 2 Duo (3.06GHz) and the $ 300 Core i5 (2.66GHz) in the United States. In addition to a desktop processor with a totally different architecture and four internal cores (quad-core), the machine also has a much more advanced graphics chipset: the ATI Radeon HD 4850, with 512MB of VRAM.
Regardless of this expected delay for the Core i5 and Core i7 models, the entire line of 27-inch iMacs is indicated with a shipping forecast of at least 7-10 working days. As we commented here on the website, the price of the computer is super aggressive, so it's no wonder that it already seems to be making a huge success out there.
