@jws The 12-inchers missed out on some features the 15s & 17s used: 10/100/1000 Ethernet; FireWire 800; CardBus expansion slot; full-sized DVI & S-video outputs & the bigger units had two RAM slots vs one & soldered RAM for the 12-in. This latter is surprising because the last of the 12-inch iBooks, with a 1.33 GHz processor has 512 MB of soldered RAM vs 256 for the PowerBook.
