New iBooks
As much as we would all love the iBook to go to G4, I have a feeling we won't see that just yet. It WILL happen of course, at some point, since the iBooks are the only line left with G3's (except for the classic iMac). I disagree that consumers would not get the advantage of a G4 chip in the iBook since OS X is now the default OS on all Macs. G4's just handle X better than G3's, even at the same Mhz.
What would be great is to see a small speed bump, to say... 700 Mhz, but with a G4, and a bump in bus speed. I know it's probably dreaming, but that's what would get me to buy an iBook for sure.
As for case redesign... why?? The current design is a huge hit. I don't see any reason why Apple would change that, at least right now.
And colors?? Not a chance! I think Apple's days of offering colored Macs are long over. I know when the iBook was first intro'ed, there were rumors flyin' arund about color models coming out, since ordering one on the Apple Store would get you to a page that said in the summary "Color: White". Anyone know if that still happens? I haven't looked for that in a long while.
Anyway, should be interesting to see what they'll release. If it does happen (new iBooks), then we'll know for sure that Apple's strategy for releasing new products when they're ready is true!
