Thank you! It looks balanced.
However (as always when these comparisons are made), people who have invested in an ecosystem (of Apple, Google, Microsoft) with limited compatibility with the others, will shrug their shoulders, as they won't buy a device that doesn't match their "installed base" of hard- and software.
(Unless they want to have a foot in the other system too. Which seems wise to me.)
And yes, if you want to compare a notebook computer to a tablet computer, you may well want to include a keyboard in the comparison. - However, in my experience (YMMV) tablets should not be confined to a keyboard cover. In late 2015, I bought both the Google Pixel C tablet with its optional magnetic keyboard/stand and the first large iPad Pro with a clamshell keyboard cover, and in mid 2016 added a Surface Pro 3 with detachable keyboard cover. Of these three, that iPad is in daily use after releasing it from the clamshell. The Pixel C would have fared better (than collecting dust) with more storage than 64GB and with fewer successors (I have five ones in two models). The Surface would have got my bet, but somehow it shouldn't have an Intel inside. (Its keyboard cover seems dead. I have wondered for some years if I should buy a new one.)
Finally: I may be characterized by the length of my comments. I enter them on the virtual keyboard of a large iPad in portrait orientation. Despite keyboards within arm's reach.
