For anybody else out there eyeing a new iMac G5, Apple has recently released oodles of information in the form of a "Developer Note". The note consists of four "chapters" (Overview of the iMac G5, Architecture, Devices and Ports, and RAM Expansion) as well as two appendices (Supplemental Reference Documents and Abbreviations). OK, so not all of it is nail biting excitement, but if you fancy technical specs, give it a nice long read.
