Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
I don't get it. They don't own any content. This isn't Sony we're talking about. Why lock us into one format? They already have the system locked into Windows for video in general! What I fear is this gives all the more reason for the hackers to have their way with the system. If they removed these barriers, they would also remove much of the motivation of the hackers.
