The reason I never liked Steam Deck is the fact it was built around graphical performance.
The Steam Deck is bulky, big, heavy, noisy and has poor battery life.
When I buy a handheld I want:
-long battery life
-low weight and portability
-no noise or loud fans
❤ my Switch.
👎 Steam Deck.
It's not built around graphical performance? It's built around utility. Just because it has better graphic performance as a byproduct to help it do it's job doesn't mean that's what it's built for. It's clearly built for being able to use it however you want. As a handheld, a computer, an emulator, and those are just the ways I've used it. The Switch
can't have that utility based on it's lack of graphic output-- it's the limiting factor. The switch is purely for real portable gaming (while I still think its a mediocre for being a portable device alongside of Steam Deck. Sorry, it's no comparison to older portable Nintendo devices) and lacks in any form of utility.
You're missing the entire point of the steam deck if you think it's for taking with you on the go like the Switch. You don't buy a Steam Deck for that. They're for taking your PC games to the bed or couch without having to sit at your computer all day. Somewhere comfortable. You
can take it on the go, but as you said, who wants to carry something that size around? (Still more comfortable to hold than the Switch, though) It's
extremely convenient in that regard. I can play thousands of games wherever I want.
The fan is also not loud at all and that's simply never been an issue. I'm lucky if I can hear it at all unless it's silent in my room and I have the sound all the way down (which I would never do while gaming). Maybe you have a faulty device, because this is simply not true.
Battery life is of course an major issue if you're playing AAA games or anything graphically intensive, but we're still in the first iteration of the handheld. Did we forget the battery woes of first generation switch? It was awful as well. In fact, it was the same as the Steam deck and offered zero of the pros other than than being lighter and smaller. (2.5-6 hours) I can easily get 6 or so hours with the Steam Deck. Not fantastic, but if I stay away from AAA gaming the battery life is satisfactory, comparable to most Laptops.
Both handhelds have their ups and downs, sure. As an adult that doesn't need to "game on the go" anymore (never does that opportunity present itself) the Switch does absolutely nothing for me anymore. Not when I can play my Switch games more reliably on a different console, which is just ludicrous.
