That new Apple Computers are to be expected for the Holiday shopping season is 100% sure. AppleInsider has a new report that helps confirm that. They report that new updated iMac All-In-One Apple computers are already in production since two weeks in Taiwan.

The new updated iMac 2009 would have a cooler and thinner case design and possibly if we are lucky finally Blu-ray drive support.
Other details are not available. Actually the new Fall iMac would be the option for me in case I decide against Windows 7 and actually switch to Apple for my Desktop computer. For that to happen the new iMac needs to pack a Core i7 CPU, else it is just not powerful enough to be a long term investment.
