I figured I would be playing evenly in handheld and docked mode. It's more like 40% docked, 10% handheld, 50% tabletop (with a stand).
It's kinda crazy thinking back to the reveal when I viewed tabletop mode as a novelty at best, but now here I am spending the bulk of my Switch time in that very mode. It's just so easy to plop the Switch in a stand on the side table (for couch or bed) and play, holding the joys-cons in each hand by my side with a podcast or TV show on in the background. Indie games in particular lend themselves so well for this type of play.
ARMs, Splatoon 2, and BOTW make up a large portion of my current play time in docked mode. I prefer to play all three with motion controls on, and TV play lends itself better for that preference. Also, local co-op and multiplayer on my switch is mostly done in docked mode. I think the switch screen is way too small to be crowding multiple people around, though it's nice to have the option when on vacation.
On another note, Splatoon 2 is the only game I prefer the Pro controller over split joy-cons for. Yes, I feel like BOTW plays better with split joy-cons.
