Ssp commented - to the point:

This is funny in a sad way. The people who don't actually have to use the stuff are 'loyal'. With MS and SAP featuring prominently I wonder to which extent the list would differ from a list of companies that do a serious 'lock in' on their! customers. To their discredit - they couldn't resist using the word Apple and fanatic in the same sentence. Good journalism or innuendo?
