Yeah I know, there aren't any uses for it at the moment. However, yesterday I had to move 45GB worth of pictures from my desktop to my laptop. I considered moving them to my external HDD using USB 2.0, but then realized it would have taken me hours to copy from PC to HDD and then from HDD to Mac. So I settled on Ethernet (connected PC to Mac directly) and even that moved at an estimated rate of 95MB/s (according to Activity Monitor) However, I think for applications such as these, the advantage of Thunderbolt becomes very apparent. It didn't hit me till I sat down to do the math that TB would have moved at 1.25GB/s (I know real life speed would be hampered by HDD read/write speed but still that's impressive) I'm pretty excited to see what kind of accessories use this port.
