Bold: A TON of advantages as you can play whenever you want. Like, in your bed, for example. Or when you're preparing dinner. A quick match of 1-2 Switch while cooking is awesome as you don't need a TV. Just an example. Or if your partner wants to use the TV at the same time like you would want to play - just play in handheld mode.
Italic: That's perfect for a lot of games! Instead of just staring through the window you can use your otherwise wasted time and play some games. I'm sure you can beat a lot of heavy rpg's that way. It sums up every day.
Bold:Why would I want to play in different rooms, if I could just play where I always play? Bed or couch, what's the difference?
Also you could just stream your Xbox One or PS4 games to a laptop if you really wanted. Or play PC games on the laptop.
Italic: Like I said that's the only worthwhile use I can imagine. But again other people listen to music during that time, browse the web or chat.
Also using numbers from the US, only 5% of the workforce uses public transportation to get to work. That's quite a minority.
