I think all the changes Apple is trying to make is to prevent them from getting stale and staying ahead of the competition. They could easily make a cheaper macbook today if they wanted to...but why would they when they don't have to. Once sales start slumping, I can see them launching a budget mac.
And I'll take it one step further:
Apple can flip the switch at any moment and release a Windows 10 Mac, preinstalled at the factory, Genius service available at a mall near you.
Remember, the iPod was a piddling nothing niche footnote until Apple released iPod for Windows and then the iTunes explosion and the iPhone revolution kicked into full gear. If Apple wants to increase notebook sales 100 fold, all they have to do is promote how good their machines are running Windows.
