I have to be honest with you. I did not know that part of the reason Apple hadn't put the G5 into their iBooks and PowerBooks was heat and power related, but my prediction holds. I don't believe they'll rev the G4 units again. It's been about seven months since the last rev, and I would imagine that if we wait another seven we'll have G5 notebooks. I wonder what we'll be up to in the desktops by then, though.

I understand that Apple is trying to focus on portability. That's great, and it helps a lot for multiple reasons. First of all, as I see it, the fifteen and seventeen inch PowerBooks are very much desktop replacements for almost any user who isn't a total power user. I'm talking about video editors here, and really they can probably get away with using one too.

When I see portability being improved, I see servers being improved. With their xServe taking up only 1U of rack space, I see these servers as having similar heat issues to the notebooks. I see the inception of a dual G5 xServe as a sign of improved power and heat.

So I maintain my prediction that the next rev of Apple notebooks will have G5 processors.
