Exactly. More like 5 year old technology in the GMA stuff. We'll see what happens when Larabee comes out. I think, though, that for every macbook user actually using their machine for real A/V work (like I did on my PB667 for a very long time) there are 20 college kids that just use them to surf, listen to iTunes, and type papers.
I agree that it seems that Apple probably sees Firewire as a "pro" feature now though, similar to the way the PPC iBooks couldn't extend their desktop onto a second monitor (only mirror). I'd say that the bellwether for this is whether it's included on the forthcoming expected Mac Mini update.
What I find annoying is that they didn't replace it with something. An eSATA port, for example, would have cost nothing & used no extra power (and not even any mobo real estate beyond the connector), and could have been yet another trademark "you saw it here first" feature (like expresscard). I suppose the same argument applies: "if you want eSATA, get a pro book & stick a SATA expresscard in it".
I'd be very interested to see an (pardon the pun) apples-to-oranges comparison of USB2 storage vs. same drive in a good NAS, a.k.a. do you get better performance with AFP/SMB/NFS over the GigE or direct attach via USB2?
