If you can find the video of the MacWorld inwhich the iBook (clamshell) was introduced, Steve had a chart that showed the PowerMac had the PowerBook and that on that day the iMac had the iBook as its portable brother. So yes the iBook was indeed intended to be the portbale iMac.
It may have been intended to be that way, but who cares? Look at the timeline:
June 1999-January 2002: Both iBook and iMac are G3 based. (30 months)
January 2002-October 2003: iBook has G3, iMac has G4 (22 months)
October 2003-August 2004: Both are G4 based. (13 months)
September 2004-January 2006: iBook has G4, iMac has G5 (16 months)
January 2006-Present date: iBook has G4, iMac has Core Duo. (5 months)
That's 43 months of having the same core CPU (which doesn't mean they're equivalent, but it's an easy benchmark to quote), and 43 months of having a CPU at least one generation behind, and for the last five arguably two.
Confused? Well, it's not really that confusing. The iMac that Jobs would have compared the iBook to in 1999 is not the same machine in any sense as the machine sold by that moniker today. The iMac G3 went down in price to around $800 in the end, and was clearly an AIO aimed at everyone. The iMac G4 changed that. It never came down significantly in price, never getting below $1,000. It was complemented by the eMac, which did get down to well below $1,000, and then the Mac mini. Essentially, the "iMac" today exists as two lines of computers, a low end machine (which has the GMA950 in it), and a high end machine that really replaces both the high end iMacs of 1999 and the Cube of 2000. It's an elegant, premium, desktop. The iMac G3 was never an elegant, premium, desktop. It just wasn't. Many people liked the design, but it wasn't considered "premium" and it wasn't elegant so much as stylish.
So you're saying, in effect, the iBook is intended to be related either to a machine that doesn't exist any more (because it's been split into two seperate lines), or to a machine that has the same name, but is actually aimed at a higher end market.
The iBook cannot, and should not, be a portable version of the iMac. It shouldn't because that means the lowest price of the iBook would be around $1,300, and that's for a machine with a lower spec than the iMac (because portables are always more expensive than the equivalent desktops. They just are. They're more desirable and as such you pay a premium.)
It cannot because Apple would be abandoning the market for low end laptops. The iBook is, like the original iMac, a low priced, entry level, value for money computer. To demand that the specs of the MacBook be aligned with the specs of the $1,300+ iMac is to demand the complete withdrawl of Apple from that market. That would be wrong.
