Looks like we still have to be patient and wait for our Thunderbolt devices to appear on the Markets. We do have the Apple Thunderbolt cable and the Apple Cinema Display with Thunderbolt. There is the Lacie Thunderbolt hard drive, even though that is a bit expensive for what you get. There are also a few Thunderbolt breakout boxes available that allow you to connect PCI cards via Thunderbolt to your Mac. What we are all dreaming about as early adopters are the single drive Thunderbolt enclosures that we can connect up and get some speed without breaking the bank.
