We must not forget that each and every Apple device also comes preloaded with Apple software. They don't sell OSX for non-Mac computers. Therefore jumping to such a conlcusion is unwarranted as every single sale of a product of theirs involves a sale of their software. When one tallies up the percentages, a sale of an iPod or iPhone is classified as a hardware sale though Apple is also selling iOS in the transaction.

In other words, the only way to consume Apple's hardware is through Apple software. Therefore, every single sale of Apple's hardware also involves the sale of Apple's software. I find it a bit disturbing that the article does not mention this.
