I'm looking at dumping my 1.25 15" SuperDrive/1GB RAM (made money back on freelance, have enough machines, etc.), and want to move to a more portable machine (12").
I'm waiting for the next revision — and I wonder — according to all the reports, ( http://www.theregister.co.uk/content/39/35749.html) it seems the power consumption of the new 7447A is just comparable to the older version. Assuming Apple puts this chip in (likely) the next bump, it sounds like battery life won't be improved.
For me, I'm not rushing, nor do I need a G5 (this year). I just want portability (reduced weight/size) and productivity (battery life). As for high-end video and image apps, I use my desktop machines.
Also: the iBook G4, albeit only 80MHz looks quite tempting; the video card is even more powerful than the Aluminum, and it's much easier to care for (I've had one): http://www.gamersdepot.com/hardware/...orcefx/001.htm
Thoughts?

Did you notice that the new chip has on-the-fly clock frequency adjustment? This feature can make a great difference in power requirements when there is no load on the prossecor.

No, I didn't notice. I wonder what the engineers think about this and average battery percentage improvements?

All depends on how efficiently this chip adjusts its frequency. It seems that there are not available details right now. With such a technology, there could be great margins for improvement in battery life.

I was going to buy a Rev.B 12-inch last fall, but had to postpone the purchase because of other expenses. At this point I am definitely going to wait for a Rev.C 12-inch, which will hopefully bring a lighted keyboard, two RAM slots, and the power savings of the Motorola PPC 7447A.
However, if you have a good desktop system, I would also seriously consider the iBook G4. Unless you need DVI-out and reliable clamshell operation, I don't think the extra money is worth it for the 12-inch PowerBook.

Until we get a 3 lbs sub-PowerBook, the 12-inch PowerBook will do.
