I am a huge Apple fan but I am happy their sales have declined. Maybe Apple will re-focus and start to paying attention to their Mac lines and make sure their upgrades are solid and big ones. Not small ones keeping a large price tag.
I am holding to my devices longer and longer. My Mac Pro is from 2011, I just updates my iPad after 4 years I think. My iPhone still the 5S.
Stop spreading all over on many industries and focus on what you have done best.
You'd prefer it if Apple made products that needed to be replaced every 1-2 years rather than every 3-4 years?
I recently bought a new iMac, and would hope that it will last at least 5-6 years.
