    Maybe Apple management is finally getting their people to fix existing features of Mac OS X instead of piling on more and more features that don't quite work right point release after point release.

    I am referring to features that a software developer would make use of, not high-level things like iApps or MobileMe.

    USB 2.0 going its "proper" speed on a Mac does not justify the lack of FireWire on the new MacBook.

    It's great that USB speeds have picked up, but...I don't really understand the methodology. I don't see anywhere in the Numerique article the size of the total transfer being done, in particular.

    I expect USB2 to have burst transfer speeds as fast or faster than FW. It's supposed to.

    I am very skeptical if they're claiming that USB2 now keeps pace in sustained transfers with FW400....

    How do I know this isn't FUD by Apple's PR team?

    Well its good their doing it for the older Mac's as opposed to the new ones. It would be nice if they would enable the four-finger gestures on the previous generations MBP's (I believe I've read that the actual chip is the same in both.)

    Thats like.. 5 years late!? But never mind.. Better late than never. I still prefer Firewire mind.
    Seems ironic that Apple get it sorted out just as USB 3 is knocking at the door.

    people have to stop complaining about firewire support on new macs. one day will come when apple products charge wireless. at the rate they are going , its bound to happen.:apple:

    USB 3.0 late 2009 at best, early 2010 most likely.

    This has nothing to do with OS X. If it did, it would mean older usb 2 Macs would now be faster too.
    This was a hardware issue.

    No, USB 2 is not supposed TO BE FASTER, IT'S BUS has a limit of 480mb of transfer vs 400 for FW. This has nothing to do with the actual data transfer speed which is on average 20-30mb for USB 2, 30-40 for FW400 and 80-90 for FW800.

    Don't know what you are talking about do you? It is the theoretical transfer speed.

    USB 2.0's theoretical speed is 480Mbps (read megabits per second). There is 8 bits in a byte, so 480/8=60. So, 60 megabytes per second. Obviously, USB 2.0 never reaches that in practise.

    FireWire 400 operates at up to 400Mbps. I'll let you do the maths.

    But you're not including overheads and lack of controller that cripples USB 2.
