Hmm... Also, does this apply to all the other ports? Does USB 2.0 all share the <480Mbit/s speed?
AFAIK, yes the USB bus is shared speed.

Yup, they also removed the FW800 on the first MacBook pro (leaving only the FW400 in place), only to reintroduce the port on the next revision. Then, with the latest, they not only removed the fw400 port on the MBP and MB as we know, they went back to that bloody Agere chipset.
In Tiger you were able to receive and send SMS's from your address book (with your hone bluetoothed to your computer, but that feature was removed in Leopard. And then, of course, there are the whole iMovie-thing. The "HD" version is crippled in comparison to the older version.
No, no. The HD version is the old version. iMovie HD = iMovie 6. iMovie '08 = iMovie 7. I just kept both of them, unless iMovie '09 really does make HD redundant.

From what I gather there are multiple USB busses on all macs, if you check your system profiler it'll show you all of them. It was even like this in the USB 1 days, my old eMac had 2 separate busses, and I think that the more modern pro machines have more. But I think that the USB 1 and 2 are placed on separate busses on the fly, so at least USB 1 devices won't use up the USB 2 bandwidth, but multiple usb 2 devices will use the same bus.
As for Firewire, it's always been a single bus, which IMHO isn't enough for "Pro" needs, it would be nice if the Pro models had at least 2 firewire busses (an 800 and a 3200 would be nice), it would solve problems some users can have, and save them having to fit a PCIe card just to plug more gear in and have it work correctly. From an audio stand point it's recommended that if you're using firewire for an audio interface, HD and DSP box (TC Powercore or SSL Duende) that you at least stick the DSP box on a separate bus, which means a firewire card.
One other thing can anyone clarify that sharing a firewire 800 bus with 400 and 800 devices does slow the rate to 400, because I keep on hearing mixed opinions on this, some say it does some say it doesn't???
MacBook:
5 USB buses (3 USB, 2 High Speed USB)
Trackpad, built-in KB are on the same bus.
IR Receiver and Bluetooth controller are on separate buses.
The rest 2 buses are for 2 USB ports. Interesting is that iSight is reported to be on the same High Speed USB bus as one of the external devices (iPod), but after I switched my connected devices (1 is mouse and other is iPod) the iSight also moved to the bus that has iPod on it.
Strange, makes me think that there's only 1 USB bus for ports :/
In every technical performance category FW is better then USB.
It makes Apple computers look bad by relying on a port that is inferior to the design goals Apple set up.
Has Apple lost its way??
Believe me, it is a question that I have been asking a lot lately. I wouldn't call it soul searching, but it's difficult for a long-time Mac user like me (since the original Macintosh c.1984), to start contemplating another system other than Apple's. But that is precisely what I am starting to seriously do now.

cool .......so d-ya reckon we will get firewire back then or what?
USB is being hacked to death like System 7~MacOS was, and we know all the issues with that one, right?

True. there changing for the worse .Yes. But I believe things are changing.
I very seriously doubt it. The next question is will it be removed from Apple's consumer desktop line, the Mac mini and iMac.over 160.000 views & over 2.500 replies ,

Apple providing a 17" matte version.
I bet that wasn't on the original roadmap until they realised the uproar they caused with glossy-only 15".
So maybe new minis and iMacs are delayed because they are furiously adding Firewire back?![]()
Steve Jobs leaving.
Haha they arn't delayed but I doubt thats the reason they havn't come out yet. USB 3.0 is about to become mainstream and Apple knows it. Plus the Pro users who actually need firewire have the Macbook Pro. Hence the hint in the name, Pro.

USB 3 is not near market ready yet. Apple isn't going to wait until it is to release new computers.
