The idea is that you can daisy-chain many devices without using a hub. Among thunderbolt devices, I believe most screens and high-end hard drives provide the two ports necessary for daisy-chaining. USB also supports this quite well, and high-end USB hard drives also generally include a port for this purpose.

It's an interesting comeback for the concept - it reminds me of daisy chaining PCs on their serial ports for playing Starcraft:

I know you can daisy chain, my point being that you get only a few ports, per $200+ device. Vs USB 3 where added usb ports, ethernet, etc is $20 a device.
