I have to admit it's getting a little monotonous, seeing the same arguments rehashed, seeing that useless adapter mentioned once every 200 posts or so.
The simple reality is that many of us (consumers and pros alike) still rely on FireWire gear (sometimes by necessity), and would love to upgrade to the new MacBooks, but can't. Will Apple change its mind? I think the decision will largely be a function of how many 'non-technical' users will be calling Apple or bringing their Macs into the store asking how to connect their camcorders ("I thought these Macs just worked?"). Not everyone, especially the large number of 'non-technical' users that Apple is allegedly courting with the new MacBook, are bleeding edge early-adopters: Just last year my family bought a basic FireWire DV cam to replace our 1986 Sylvania VHS camera

. At least I can stop my family from 'upgrading' to MacBook that will render our 1-year-old video camera useless. What will be Apple's response to those that come in asking how to connect their cameras?
Employee: "Sorry, you have to buy a new camera."
Customer: "But I just bought mine a few months ago!"
Employee: "Sorry, but you didn't buy a camera with an interface that was popular enough."
Customer: "... so how much do these new cameras cost?"
Employee: "$150 for a tiny camera that has half the features of your current camera... or $500+ for a similarly featured camera."
The number of customers who say "Here, you can have your MacBook back, I'll buy a PC that I can actually hook my camera to" will determine whether Apple puts FireWire back in or not.
