Belkin is finally shipping their Thunderbolt Express Dock, so USB3 is now an option.
I prefer FW800 and got a used SanDisk CF reader from LensRentals used side when it pop'ed up for $26.
Sadly, my Macbook Pro is pre-Thunderbolt too!
I know. An upgrade is definitely on plan; in a holding pattern for when the new model based on Haswell is announced.
