Thinking of possibly getting the next generation iMac. Had a couple of questions. 1. With the (assumed) inclusion of Tbolt, will the current generation cinema displays work with future thunderbolt peripheral daisy chaining? I realize they use the same physical connection but I'm wondering if a mini displayport cinema display will work in the future if I end up getting some Tbolt mass storage and want to chain them together. (just to be clear I'm talking about a cinema display in addition to the iMac screen) 2. I have some wonderful logitech 5500 surround sound speakers that I'd love to hook up to an iMac. With the lack of optical and more than 1 audio input, are there any other options for surround sound speakers and an iMac? Just software emulation through a usb sound card? Thanks for your time.
