Ok, forget the g5 in a powerbook, we know it will happen, just not soon. BUT, what if Apple has spent the last 9 months (well, longer than that) upgrading the powerbooks to run on fuel cells, or AT LEAST, reworking the power system to be compatible with upcoming fuel cell technology.
I'm getting sick of the rumors and speculation about the new PB's, but I thought this was a crazy idea that may actually have some merit, if not in this revision, sometime soon.
