To be honest I'm not sure how to browse if you haven't installed the game. If you want to copy from another game you can save the configuration as a template and then import it to the other game.
Bluetooth headphones are solid now, as long as you have something that supports aptx HD and LL (HD for music, LL for movies/games). But yeah they're not cheap.
I have a Steam Deck and was considering "upgrading" to something that has more power.
But then I wanted to play Torchlight 2, an action-rpg designed for mouse and keyboard that does not have controller support. I wasn't even going to try it, but saw that Runic Games had an input profile for it. The left stick controls your character like it supporter controllers, but it's all using the mouse. The touchpads work for precise targeting. And I'm able to use all 10 skill buttons using modifier keys and adding the back buttons. Plus I was able to easily adapt this to Diablo 3, a non-steam game without controller support.
If you want to be limited to games designed with controllers in mind, go for one of the alternatives. But if you want to be able to play mouse and keyboard games, there's nothing that competes with the Steam Deck.
And even if it's on their printed menu, you might look at the menu on Google Maps and see one place has a dish for $20 and another place had the same dish for $24. You go to the cheaper place and sit down and see the 18% fee. Are you necessarily going to leave and go to the other one?
Music services are almost a necessity to me because of the amount of music I listen to, but it's also a different animal. They all have mostly the same library, so you won't typically be subscribing to more than one.
The problem with streaming video services is that most people watch a couple genres, and there's content in every genre on every streaming platform. I watch a lot of scifi, for example. So I would need to subscribe to Apple TV for Silo and Foundation, Paramount+ for Star Trek, etc...
It happens on Edge but not Firefox I believe. My work laptop defaults to Edge (and we use all Microsoft Web services so I haven't cared to switch the default) and Google services prompt to try Chrome there.
Edit: I just checked and it doesn't seem to be there. Either I imagined it or they removed it.
It sounds like you haven't used a user friendly Linux distro in the last decade. Mint and Ubuntu will install any proprietary driver you need, but even beyond that most WiFi cards are supported out of the box by the Linux kernel now.
I get Kenya even if I am in an private window and not logged in.
