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!"
it's a Microsoft product. Get over it. After you spend your hard-earned $400 on the console itself (a device Microsoft will likely lose money on anyway), the software giant need never see another cent from you. But because Xbox 360 is a next-generation console with better-than-PC capabilities, the PC ports available for that system are first-rate, identical to the PC versions. Today, that's titles like Quake 4, Call of Duty 2, and King Kong. In the future, Half-Life 2 and other titles will be added. So if you're looking for the full experience, but don't want a PC, and could conceivably rally around playing these games on the biggest screen in the house, Xbox 360 might just be the obvious solution.
