Yes, and...?
As you've noted it's a good business model.
I don't like Steve Jobs, I dislike his brainwashed fanatics and products but kudos to Apple for clearly getting it right.
their CEOs haven't shown up here to post news about how they totally tweaked Ubuntu to look kind of like AOS4 and demand our adulation for this incredible feat.
Judge the company and the products, not the CEO. OSX is just Linux, Android is just Linux, IE is just Mosaic, a number of car makes have Volkswagen engines... it's certainly not something to get pissy about and needs to be put in perspective.
