What a annoying feature this will be.
Why do Apple insist on trying to build software that does basic organization and attempts to do the thinking for us. I don't want all apps on all my devices...
This is on the same annoying level as Lions "Automatically open windows on a restart" feature that angers the world. It took them 12 months to fix that...
Why don't they focus on fixing the crappy bugs in the browser and You tube viewer to make the software more stable, over finding more pointless features for the lowest common denominator.
A big Grrrrrrrrr... from me.
Solution: When it asks you if you want to enable automatic downloads, click "Close".
