The G4 PowerBook will go down in price, no question. But it will be relatively difficult to find. You'll have to go through MacWarehouse/CDW or some other online/phone retailer. I was thinking about that strategy for myself.

Shimmy, I've heard that the Centrino chips are not all that. They do preserve battery life initially, but within a few months they get a little wonky. I've heard that the Pentium chips still have better life in the long term. Actually, the guy that told me this about Centrino said that the best way to go in a PC laptop is to get one with an Intel Celeron. Faster than Pentium and not nearly as wonky as Centrino.
