Actually, I think Apple would love that. Decreases their manufacturing costs. :)
And many other things would go up in price with a depressed currency in general.
Why wouldn't Apple like this? Their manufacturing costs would become much lower, and they would rack up even more billions in profits.
Tim Cook has already made a big deal about "currency headwinds" to explain Apple's slowing revenue growth.
Maybe not as profitable due to exchange arbitrage, but still profitable since the costs go down exactly as much as the retail price does. Engineering for the Chinese market already exists due to all the other markets, so it's essentially money left on the table if they don't.
