Depends for whom.

I got a 2-in-1 ThinkPad L390 Yoga, and for me, that's absolutely awesome. But the S10+ weights only 571g, this ThinkPad is 1.54kg. I personally don't mind the weight though.
And the keyboard is already built in. It kinda sounds like you're basically searching for a laptop.

Originally, I thought I wouldn't even use the touchscreen, I only took it as I heard that the yoga version has better display colors, but oh wow does it make sense on a portable device. Something like viewing a map makes far more sense, it's also better for scrolling and in KDE Plasma I also have gestures for nicer window switching.
And I can also just use it as a full on tablet if I flip the keyboard around.

Never have I thought I'd want laptop with a touchscreen, but now I don't want one without it.

Not exactly what you're asking, but here's my 2 cents:

I've had a couple of android tablets over the years and always buy android phones, but in my experience generally even a refurbished 3 year old iPad is a better experience than even the highest end android tablet.

Unless something has drastically changed over the past couple of years, the biggest issue I found with android tablets is most of the apps are just enlarged versions of the phone app, with no real consideration for making better use of the bigger screen. This had the effect of not really adding much versus doing something on my phone. Nearly every app I use on an iPad is correctly designed for the screen size and consequently I make much more use of it.

Google really dropped the ball on its tablet ecosystem and they're not doing nearly enough to combat the issues.

Honestly, yeah.

A tablet is going to be a great media device, you can game on them, and that works best with better hardware. It just does.

After experiencing AMOLED burn in on my current phone (Samsung A53, faint outline from the keys on the keyboard), I'd have a hard time buying one again.
