FWIW: I called AplCare this morning. The guy I spoke to seemed kind of rushed and like he was just reading something, but he said that the current 12" iBook (1.33MHz, etc) would run only OS 10.4, which it ships with. And FWIW the previous model (which he said was M9628 model number), 1.2GHz, will run 10.3 even if it shipped with 10.4. > > At 11:13 AM -0500 2/27/06, Tom R. no spam wrote: > > >The specification for the current 12" G4 iBooks (1.33MHz, > > >scrolling trackpad, sudden motion sensor HD) is that > > >minimum OS is 10.4.
