After reading articles in places like Think Secret, MacRumors, and just by keeping current on Slashdot, it's obvious that many of you guys don't know what you're talking about. At all. Norse got some of it right, like by mentioning that the single-core Yonahs won't be out for a few more months- they won't be in the new iBook. It is foolish to assume that Apple would choose to use the current single-core chips the latest revision, as some people on this forum suggested. The Yonah chip is to be introduced on January 5- why would Apple release a notebook with an outdated chip after Intel's launch?
Some people look to the price of the Acer notebook as an indication that using a dual-core Intel chip will be too costly. That is just wrong. First off, Acer is using a 2.0GHz chip, while Apple would likely use the 1.6GHz variation, which comes out to nearly half the price of the Acer choice according to Intel's pricing guidelines. The Acer product is also shipping with a 512MB video card, 2GB of RAM, and a 15" screen. Once you bring that graphics card down to size, equip it with 512MB of RAM, and shrink the screen to a 12" display, Apple can definitely get an Intel iBook out of the door for $1000.
I like Norse Son's analysis of the situation, except for a few points he makes about Apple's techincal challenges. Apple already utilizes DDR2, SATA drives, and PCIe graphics in the latest PowerMacs and iMacs. If you referred to the challenge of providing this in a laptop form factor, my apologies, but these are all hurdles that are in the past.
Another point- there is no reason to suspect that Apple would drastically change price-points of its iBook and PowerBook lines. The iBook might drop by $100 or so in the lowest model to compete with the low-end HPs and Gateways, as Think Secret suggested, but it seems to me that Apple has settled on some stable price-points that make sense: $1000 for the base iBook, $1300 for the jazzed-up model.
Just because the PowerBooks still use outdated and slow G4 processors will not stop Apple from releasing new Yonah-based iBooks. The PowerBook line is differentiated by the inclusion of Gigabit ethernet, FireWire 800, big, high resolution screens, and a much tighter 1" form factor. It's not all about speed for profesional applications. Releasing nice iBooks won't cannibalize sales of PowerBooks too much at all, I think. Besides, historically, the latest iMac G5 came out with a lot of updated hardware that the PowerMac didn't get until quite a while after, including DDR2, PCIe graphics, and updated G5 processors. I don't think that really hurt PowerMac sales- the two product lines are different beasts, as are the iBook and PowerBook.
Here are some things that I think will make this Intel iBook really attractive:
1- Ability to dual-boot Windows: You won't be able to buy an iBook with Windows and/or Mac OS X. Ever. But, Apple is on the record as saying that it would do nothing to prohibit Windows from booting in its Intel Macs, and within days of the first iBooks shipping, there'll already be people bundling Windows driver packages on the internet to get Windows to run smoothly on the new iBook. Even if you choose not to install Windows on your iBook, moving to the Intel architecture means that a program like VirtualPC will allow you to run a Windows session at full speed, making Intel Macs a great fit for corporate/power user environments. With one notebook, you can run a great and stable OS (X) while at the same time have access to everything in the Windows world, in one neat package. I greatly look forward to this.
2- Speed Increase: Despite what people say about the efficiency (or lackthereof) of the Rosetta emulation layer, I have read many good things about it from developers running the 3GHz+ P4 developer kits (which, btw, are slower than the 1.6GHz Yonah chip). The latest builds of OS X for x86 support G4 emulation, something nobody really expected, and people are reporting emulation speeds to rival native speeds of G5 Powermacs. These Yonah iBooks will be hot- blowing any G4 piece of crap out of the water. My sister has a 1.4GHz iBook G4, which is a clunker compared to my 1.8GHz G5, and isn't really that much faster than my 800MHz iBook G3 that I'm typing on right now. These new iBooks are going to be MUCH faster than anybody expects from an Apple product, especially in the entry-level line.
3- Heat Management (I hope)- I know laptops get hot. But they don't have to. Current PowerBooks and iBooks get very hot after normal use, as do many laptops. It's my hope that since Apple is revamping the entire design of the iBook anyway, it tackle laptop heat dissipation in a smart way. Of course, I doubt this will happen.
That was a lot of typing. Let me know what you think,

Addendum, I don't mean to be harsh, but I do speak out of frustration.
