640x360 is a good compromise resolution, not a bad balance between res, bitrate 
& 
filesize, and device compatibility.

It will be passable to many people on a larger screen via Apple TV, but your 
720p version 
should be noticably better.

There are still some users & devices that will struggle with h264 in general, 
but most will 
be ok with 640xwhatever videos.  1280x720 or higher, some will struggle with 
cpu use, 
and such high resolutions are likely a hinderance rather than a help to 
portable device 
users.  

But also bear in mind that the tone of that email suggests Apple is desperate 
to get people 
to move beyond 320x240 more, as that low a res starts to look bad on the Apple 
TV. So 
they are mostly targetting people to move their res up, not down.

Jay that Apple video loks like quicktime, at a guess they have hidden the 
quicktime plugin 
controls and used javascript to make nicer looking controls.
