just to make a point to all those demanding USB3 ... INTEL the company behind the USB spec STILL hasn't rolled out a chipset with 3.0 baked in.. Now, since we all know that Apple has based all of it's Intel based mac's on intel designs... Not having USB isn't that shocking.
I never understood why this is so difficult for people to understand. You can't implement what your supplier doesn't have. As to third party USB3 chips they only started to stabilize late last year.
Now if someone where to ask is Intel making a mistake dragging it's feet with respect to USB 3, I'd say yes! Frankly I don't see it competing with Thunderbolt at all as the two standards aren't even in the same league.
For Apple USB 3 isn't a big deal as there are well supported Mac alternatives.
So what is "rip lock"? I don't really use my optical much at all but have had little in the way of problems with it.
