I'd say more like a 50% user base.

I'm going on a limb here, but nowadays, 60% of macbooks (mainly the pro) are used for software development and 30% for creative work (video and editing). While something like half of those professional applications would be fine with the 9X, the other half would be left hanging for a better machine.

However, if they want to make the switch in the near future, I think that the new MacBook will first be released with an ARM processor. This way they won't alienate their core market and they will have a testing ground. Then, I'd predict two or three generations until the pros catch up.

They have the money, if they want to change to ARM it won't be Carbon stopping them.

Those numbers sounds wildly off to me. I'd be shocked if even 10% of MacBooks are ever used for software development of any kind. They are mostly used for web browsing and Office.

Your numbers are way out on a limb.

In a single year, Apple sells more Macs than there even are software developers in the world.

College students alone form a much bigger market than software developers.
