Last week I hooked up a new iMac to 2 new Thunderbolts...one on each side. The cable on the left Thunderbolt only had a couple of inches give when plugging into the iMac in the middle. I took them all back because I couldn't stand the glare and the lower height on the Thunderbolts, and decided to get a new Mac Pro instead so I could hook up 4 of them. One problem: the cord wouldn't be long enough to hook up 4 Thunderbolts unless the Mac Pro is set up in the middle with 4 screens circling it. If I set them up on my desk, there is no way for the cables to reach. Crazy. Now some may say that there is a 6' mdp cable that you could hook up but then you lose all functionality of the ports on the back, the whole point of the Thunderbolt display. Apple needs to make a Thunderbolt display cable extender...but it appears it doesn't exist.
