Apple does not bake their own silicon
They use the likes of Samsung and TSMC to do it for them.
Other than that, it seems that the writing is on the wall. If they don't manage a specucalar turn around their high end (and thus the bigger profit margin) devices will become a liability.
At the bottom end, can they really compete with the likes of Lenovo and Xaoimi?
It appears that they can't, Then IMHO it looke like Samsung Mobiles will become a niche player much like HTC etc
Now if only the Google devices were more widely available.
