How about WMP/WMA? I know that the AACs I buy from the iTunes music store have a very, very light form of DRM (like being able to burn a playlist ten times before having to make some sort of change to it), but it is very light indeed. In fact, I can't imagine why an honest person would really want/need to do the (very few) things it blocks. WMP/WMA, on the other hand, are not to be trusted, if only for the company behind them. Call that an MS flame if you will; I just say that there is such a thing as empirical evidence.
