Their market share is rapidly falling wrt Android. There's no way they can maintain that profit share if this continues and they know it.
BTW, I just wanted to say you have a GitHub link on your HN profile that leads to a 404. I thought maybe that was a mistake and you might want to fix it :)
Thanks for heads up on github. Fixed.
The fact is that they never took an early lead with the Mac [1]. They did take an lead with iPod. See how that worked out quite well for them.
