There's a piece in Andy Grove's book ("Only the paranoids survive") where tells about realizing that sales of memory are slowly going down - it's still comfortable for everyone, but at this right he will be fired by the board in a couple of years. So, he thinks "my replacement will get a carte blanche; what will they do?" and realizes that it would be "concentrate on microprocessors", a small but slowly growing Intel business -- a completely heretic, "hail mary" at a point that still doesn't seem so bad. So that's what he does. On the other hand, Intel sold their ARM business about 20 years ago because it had lower margins than they liked (and in fact, axed a lot of relatively low margin business). But, as they are slowly discovering - someone WILL eat your margins, if it isn't yourself, it is someone else.
