Not to mention xbox 360 can download hd content without the use of a pc..

And act as a PVR with a Media Center PC or Vista Ultimate..

So basically for $100 more I can get the functionality of the appletv + a PVR + a great gaming console and I don't have to mess with iTunes.  The extra $100 is almost worth not having to mess with iTunes alone.. Smiley
