All of which are challenges and costs that other manufacturers have to overcome as well.
It doesn't change the fact it's a notable drop in their profit margin.
As for it being forecast, clearly the market expected Apple to overcome the challenges more effectively than they did.
That's actually incorrect as the other manufactures generally do not buy and own equipment for their suppliers. The other manufactures didn't have 4 or so new products to ramp up during Q4. Literally everything that could have been against them was and yet they still did amazingly well. This Q1 should see major sales from China.. so although they are forecasting nothing major I think they will be ok. I'm happy knowing my shares are still worth double what I bought them for..
Also a profit per share drop of -$0.06 is hardly anything to talking about!
