regarding iMac 27-inch Mid 2011 (Thunderbolt Display Interface) At the moment there is an adapter/converter/scaler to plug a PS3/Xbox/HDMI Device into an iMac to use it as a display in HD (720p, possibly 1080p). The Blackmagic Design Intensity range will work. http://www.blackmagic-design.com/products/intensity/ The Intensity Shuttle looks the best value for something that will work. But this is starting at US$239. It also looks like it has a bunch of features for people working with film that are not needed. Does anyone know of any simpler, and less expensive, HDMI to Thunderbolt coveters? More Thunderbolt products are being released there should be something soon at least.
