A few folks on our team have been hard at work on an ultra-cool flash-based “Media Center 2005 Design Studio” that helps you pick exactly the hardware you want for every room in the home and beyond. Just drag and drop devices like a living room PC, a portable media center and extender, tell it what type of cable/satellite connection you have and it will create a shopping list that you can email or print- even including pictures and recommendations on common cabling for setup.
Whether you're interested in a Media Center for the living room, bedroom, home office, or wherever else, check it out and give us your feedback. It's a v1 and will get better, your feedback is appreciated.
