I don't think this guy understands what innovation is. The Steam Deck and Wii aren't particularly innovative. The Wii is a bit unusual, but pointer controls didn't stick (though gyro controls have, in a minor way). The Steam Deck is just a regular handheld but with an x86 CPU.
I don't think people are going to buy small consoles to play big games. And a powerful handheld is overkill to play small games. If people want to play small games, they use the phone they already have.
The handheld console sweet spot is slightly more powerful than the Switch. But the Switch's selling power isn't its hardware, but its library. Nintendo games have selling power. And even outside of that, the Switch has a surprisingly large library of third-party games like Skyrim and Doom. But if people really want a console that will do everything, they'll get a Deck, because I know you won't be able to do whatever you want on Microsoft's handheld.
