Popular Science put together their list of the 100 greatest innovations of 2018.
One lesson learned from Apple recently is that if your products stagnate people will start to look around, and when they do that they may spend their money elsewhere.
As just one small example of this, iOS got boring for me, so I started looking around and bought an Android tablet instead of a new iPad. These days the Mac and macOS feel stagnant — or worse than that, moving in the wrong direction by removing features like Spaces — so I’m looking at desktop alternatives as well.
2018 Update: As a result of macOS moving in the wrong direction (IMHO), I now have have a laptop and desktop that run Linux Mint.
