Even though the wire xfer speed of usb2 matches FW, in practice there is 
more CPU overhead and you probably won't match the disk throughput.  And

I interpreted Apple's move of dropping FW on the low end laptops as a 
means of forcing serious users to buy the more expensive pro models, not 
that it is going to go away.
