I think Apple won't accept BTC. Because, BTC is riskier than cash, BTC impacts on the activities of Apple.
Might be they are not willing right now but a time will come when they will welcome bitcoins to be used in apple products. There is no doubt in this statement that bitcoins are a lot more risker than gold and cash etc. But the thing is we all are still loving them because of their amazing nature and behavior towards a common man. We are living better now just because of them.
