It's the opposite. While they should have dumped the Mac mini, cMBP 13", iPhone 4s and iPad 2 long ago, iPods too, they should also have made:
3 iPhone models: 4", 4.7, 5.5
3 iPad models: 7.9, 9.7, 12
1 MBA: 12
3 rMBP: 14, 16, 18
iMacs are good
nMP is good
But clearly they could enter:
iWatch
TVs
Cars
Fiber/4g networks
mobile payments
Selling power and datacenter space.
Instead of throwing away money to greedy shareholders, they could use those 60 billion to fulfill great possibilities.
