The figure of $46k is extracted from the site Simply Hired. If you go to the source of this supposed stat (http://www.simplyhired.com/a/salary/search/q-apple), you will find that it is simply a search for jobs with "apple" in the title or description.
If you go to the URL of search results that are used to determine the $46k salary (http://www.simplyhired.com/a/jobs/list/q-apple) you find that of the first 50 listed jobs, only 4 are actually at Apple.
Of the Apple jobs, 3 are at the retail Apple stores.
Of the remaining jobs, while many are tech support or development on Apple platforms, most are completely unrelated to Apple. They are jobs at Apple Bank or in places like Apple Valley, CA, or at Apple Blossom Mall, etc.
My god, and to think that some these people have the nerve to call themselves journalists? If this is what passes for news these days, I weep for the future.
