Bose takes a technically sound idea, rebadges it, claims to have invented it, and overprices it...this is the process behind the Wave Radio and products like that.
They also make some very dubious claims, such as their 3-2-1 "surround system" with only 2 speakers...yeah...that makes a lot of sound technical sense.
For what they charge, you don't get much compared to DIY or piecing together components yourself. But then again, most of the ignorant masses don't have the knowledge they need to do that, and Bose provides a warm and fuzzy voice selling them a product that they don't need to think about.
