I read an article on the Bose suspension this past week. Looks pretty interesting to me. I happen to be a Bose fan for what they have done in the audio industry. The guy seems to know his $hit and thinks outside of the envelope. He also does his R&D quite extensively to make sure things work.(Hence their big price tags) This will be an interesting technology to watch grow.
