Agreed. USB is processor dependent thunderbolt is not. USB Superspeed is 10GB's total in and out. Thunderbolt is 10GB out and in simultaneous (two channel can output/input at the same time at 10GBs both ways). Also intel invented both. Thunderbolt is in its first incarnation, the second is about to be released with even faster speed simultaneous in and out. Slated for early 2014 is the release of the 20GBs Thunderbolt controllers. Thats dual channel 20GB.
