What Is The Current State Of SDMI On The Market?

theancient1 asks: "With malls already decorating for Christmas, it's time to start thinking about gifts. Since MP3 players are making their way onto more people's lists this year, I thought this would be an excellent time to get a round-up of the current state of SDMI with respect to current hardware. Are any players currently looking for a watermark within a standard MP3 file? What restrictions do current players have on what I do with my music? To what extent are the popular vendors caving to the demands of the recording industry? Numerous vendors are advertising their players as 'SDMI compliant to allow you to download music from major labels.' How can we get the message across that SDMI is not a feature without a price? I'm looking for some good Web resources for the average non-geek consumer."
