How Macs Work, Millennium Edition
John Rizzo, K. Daniel Clark
I would love to read an updated version that includes the later G4 laptops and G5 desktops. However, if you're truly technically oriented, you may find this book over-simplifies too much and glosses over many details. I found it useful for explaining the physical operation of hard drives and CD-ROMS, but found its explanations of computer architecture and software lacking.
