I decided i wasnt going to read a whole 8 pages worth of stuff, so im gonna point this out here and now. When you check the source, eg DigiTimes, you will see if you look closely at the chart, you will note that it says they will ship the iBook/iBook G5 and a PowerBook G5. This leads me to belive that they will still be shipping the G4 model of the iBook. It also leads me to belive that they will only have certain models of the iBook G5 as an upper class model, and seemingly, they will change the entire line of PowerBooks to the G5 chip. Personally, based on this conclusion, it looks as though by doing this, Apple will boost sales of both iBook and PowerBooks because of the extreame difference in the two. Such a difference has been lacking, in my opinion, since the introduction of the G4 iBook.
