i was just thinking about ibooks and why there has not been a revision in a little while now. other then the fact that the 1ghz g3 are avaliable, the ibooks have to be able to boot up in 9. why do you ask.. because a lot of education customers need to still boot up in 9. working in a high school we are a bit nervous about jumping to 10 when 95% of our systems run in though we understand that a move to 10 has to happen we would like to delay it as much as possible. hard to embarce change as a lot of people well be greatly disrupted with the move. just a thought on why we have not seen a change. also i hope the 1 ghz machines can boot in 9..
