Expecting a company that sells tablets to also provide tablet-oriented interfaces for the OS and major apps isn't unreasonable. But Google hasn't shown it is willing to provide those interfaces. My Android tablet advice still stands - I'll take Android tablets seriously once Google does.
All the interface regressions since Honeycomb still make Android tablets feel like an afterthought. While the Pixel C is a great demonstration of these problems, it's still not a great productivity device compared to the competition.
The side-by-side comparisons between Honeycomb and Nougat are damning. "Regression" isn't an adequate enough word for what's happening here.
