Well, Switch obviously is both, that is not so difficult a concept. Just as humans are both animals and bipeds. Things can be categorized multiple times, these categories often aren't mutually exclusive.
I know it is, what I'm against is to make direct comparisons with older generations
This is a classic mathematic problem of comparing sets with elements in common
In 8th gen or before you have the home console and handheld market very well outlined.
In 9th gen, not anymore with Switch counted for be it can deliver a false impression both segments are growing, when in reality is just Switch counting twice
Torture the data until they scream what you want them to display I guess...
