NetFlix on the Wii. $9 a month.  Great, just what the doctor ordered.  Except that, like the PS3, you have to put a CD in the Wii’s drive in order to actually watch the movies you rent.  A MacMini or AppleTV doesn’t suffer that characteristic.  Usability, guys.   Same thing goes for you Amazon–if you’re going to compete with the ecosystem king, you better do it by beating them at the thing consumers care about most. Usability.
