My Surface Book 2 13" is no way as nice to use as an ipad, even for consumption. It gets quite hot from mild use and the displays touch function is noway near as good as an iPads. It is a nice idea but poorly executed. It also lacks most of apps that I use on the iPad to read papers etc.
This has also been my experience using Surface devices in tablet mode. Apple absolutely does need to do more with iPad OS but it needs to do it the right way. I have a feeling they're already down that path but its going to take a little more time before we all see it. Splitting off iPad OS was step one.
