One thing that would really make the circle complete, would be TB storage options for your primary device, like a laptop that has room to nest the TB with the lid closed, or a tablet case/cover that can accommodate the TB without having to collapse it.
Many smart covers for iPad already have the magnets in them, throw a few more in there in the right spots and boom, your TB will stick right on there, so you can run quick to your next meeting, plop your iPad down and jump right back into your work just a few seconds faster. Unless of course you are addicted to the take down and set up process. For me though, I am constantly being asked to access information at random times, without being able to reliably predict how long it will take or how much typing will be involved, so that kind of access speed along with a versatile portable (lap friendly) typing surface would be incredible.
That being said, none of us will truly be free until the iPad can run a desktop OS (without virtualization!).
