Im not sure what happens to the data, but the mini store is NOT spyware.
And the comment about apple forcing OS registration harder than microsoft is not true, when you start OS X for the first time You are submitting your Hardware Serial number to apple to Register your computer so apple will know how to track your warrenty information. OS X itself is never registered only the Mac itself
I see how quickly the forum turned anti-apple after I left for a few months
