Sony Marginally Less Stupid, Takes Nearly Meaningless Action

Sony usually provokes a mixture of anger and joy as their digital media projects miss even the most basic elements of common sense.  Finally, Sony is slowly, hesistantly, and partially allowing MP3s to be played on some of its players.  Sony still seems to have no coherent strategy here.  Why on the flash players and not the hard drive players?  Why is ATRAC better and why must they push it on their music store customers?  Why not mention the lock-in ATRAC has to Sony devices, even after they adopt MP3?
