Seriously - the iBook is an iMac to go!! So why is the iBook basically a Mini with a screen!!
When have the iBook specs ever been comparable to the iMac?
The iBook is Apple's entry level mobile. The iMac is a mid-level (albeit, still consumer grade) desktop. Aside from the similarity in their names (which I guess is about to change), there's no reason to think they should be comparable.
Anyway:
1) They should, IMO, keep a sub-$1000 model.
2) The low-voltage chips are not Intel's entry level (Core) chip. They won't be in Apple's entry level portable. Low voltage is actually (a certain kind) of high performance chip.
3) They'll have the new bells and whistles (MagSafe, iSight, frontrow, remote)
4) Just like before, they'll be differentiated from the pro machines by optical drive, video memory, processor speed/type, hard drive speed and capacity. Perhaps also different screens and the ability to do extended desktop (although I think it's way past time all mac portables do dual-display)
Who knows about form factor. My guess is there will be both pro and non-pro versions of the ~15 and ~13 inch portables, and only a pro version of the 17".
