Hi folks, I'm thinking of buying one of the current 20" Intel iMacs, and I'm wondering if I will be able to upgrade the 2.0 Core Duo to a Merom after they are released. (I understand that opening up an iMac will be difficult, but that isn't my concern.) I understand that the iMac is socketed and the current Core Duo will be pin compatible with Merom, but realistically, will I be able to buy a Merom chip a year from now and put it in the current iMacs? Thanks folks! The Mac community rocks!
