Apple is sort of like a BMW. Has cost and prestige written all over it.
As long as people have spare money to throw at their prestige, it will do well though the recent bulk of sales is fleeting.
The problem for Apple is that the "new" has rubbed off. I mean the new of the iPhone form, and the iPad form.
I will put it in a more personal way. Women and men are always impressed with the latest model car. It's been that way for ever. Computers, tablets not so much. The phones are just a bauble for some people. They will move on to the next new shiny thing.
