Not going to happen, most Windows laptops and desktops now have firewire (finally, and it took them how long to catch up?).
Well, I really needed a newer laptop, I got a cheapo $499 Compaq special from Staples (total with shipping and tax after rebates and price breaks). Thought I would go ahead and wait for the PowerBooks to go Intel before getting one (I think the iBooks and Minis will go Intel first). I have an iBook G4 and it's getting so much use, it's not holding up well. The Powerbooks are more rugged.
My new Compaq is nice with a 14" widescreen, DVD-ROM, 256 Megs RAM, Intel Media 900, 40 Gig HD, and full keyboard. Hopefully, the new Mac portables will be the same (I thought I wouldn't like the screen as much as a 12", but I do as it's longer).
My point is that this new cheapo laptop DOESN'T have firewire. I can see if Apple drops firewire, it will only be on their cheapest laptop (I understand they've always had an inexpensive iBook with only a CD ROM, for budget reasons).
I can see and iBook 13" Widescreen with 512Megs RAM, 40 Gig HD, and and Pentium or Celeron M with Intel Media 900 go for about $599 without the firewire. The upper models with larger hard drives and faster processors will have the firewire too.
