personally, I see the PB as the first with an Intel chip, at least the first laptop. Why would apple make a big deal about how much power we're going to gain with this switch to intel, only to not wow us off the line. Powerbook opens the door with the fastest intel chip the Yonah family has to offer, then later on release slightly slower, and/or single core ibooks, keeping a definitive line between the two product lines. Mark my words, they'll have to go big first. in the mac community right now, you can't get bigger than a new generation Powerbook (G6?).
