I've been thinking today, I'm running out of USB and firewire ports on my 2011 iMac 27". Wouldn't it be great if there was a thunderbolt hub that had maybe 10 USB ports, a couple of FW800 and FW400... Does this already exist? If it doesn't... why not? Surely there would be a massive market for something like this. Anyone know of anything or anything soon-to-be-released that would do the job?
