So it seems speed (twice as fast as usb3) and daisy-chaining is what's being hyped. Does anyone else think that the speed really is redundant at this stage? Most people are still sitting on non-ssd drives, and would barely be able to push 100mb/s read/write. Transfer a HD movie in 30 seconds? Cool. Your disk will still need 2-4 minutes.
All I keep reading is "imagine this would be everywhere. Wouldn't that be awesome?". Well... yes, it would. But it's not.
For data, no. Not much offered over USB 3.0.
I think for expansion capability this stomps USB though. I could see it taking over for pretty much everything but graphics cards, keyboards, and mice.
Also USB 3.0 has an advertised speed, where Thunderbolt claims it to be actual speed. And since there're two channels it's more like 20gbps.
