I'm sure the Switch 2 will be a great home console but when it comes to being a handeld device it fails in every way possible
Portability
The Switch 2 is estimated to be around 11 inches wide (with joycons) and that's simply too big to use outside. The og switch was already too big to put in your pocket so there's no way you can put a switch 2 your pocket
So not only you need to bring a carrying case but holding such a big device whilst outside isn't going to be an enjoyable experience
Home Console games
Because of the hybrid nature of the console the games aren't made with the same pick up and play game design compared to the games made on previous nintendo handelds
Mario kart ds and Mario Kart 7 are better portable games than Mario kart world because both those titles were designed around portable play (especially ds)
Series like pokemon and animal crossing peaked on traditional pocketable handelds because their games best suited that style of play
Affordability
The switch 2 and games are priced like home console devices
Nintendo handelds used to be an affordable way to experience the current Nintendo eco system but that philosophy has died post switch 2
