Anandtech posted a review on the Apple Thunderbolt Display
Ever since I moved to a notebook as my main work computer I've become increasingly annoyed with the process of actually moving my notebook-as-a-desktop around. When at my desk I've got DisplayPort, Ethernet, two USB, FireWire 800, speakers and power all plugged into my 15-inch MacBook Pro. What makes it frustrating isn't the first-world-problem of having to unplug seven cables, rather that it doesn't need to be seven cables - Apple could make the whole thing happen with just two.The Apple Thunderbolt Display Review
Every Mac released in 2011 has at least one Thunderbolt port (the iMac has two), and Thunderbolt can deliver exactly what I'm looking for. Thunderbolt can carry two things: PCI Express and DisplayPort, the former for data and the latter obviously for video. Why would you want to carry PCIe and DP over a single cable? To address problems like the one above.
