This is exactly why we have these issues like we're dealing with with the Switch 2. Console gamers are only focused on hardware and exclusivity, they're not focused on the operating system of the device, the build quality of the product itself (including the ergonomics), nor do they care about the company that produces it beyond their basic fanboy tendencies.
Steam Deck's competitors might have slightly better hardware or a higher resolution, but none of them are right to repair friendly. None of them have custom software literally designed for the product, and none of them have the sort of ergonomics that the Steam Deck has. Not to mention the fact that Valve is an American company, which might not be important to everybody, but it is important to me. They're also a company that has proven themselves to be largely consumer-friendly.
While I'm not dissing anybody who does make the choice to go for an Ally or a Legion Go, the problem I have is that those devices are literally just another hardware company jumping on a band wagon. The Steam Deck completely revolutionized the way that we play on PC. Sure, it took inspiration from the original Switch. There's no question about that. But that doesn't mean that Valve was just jumping on a band wagon the way that ASUS and Lenovo are doing.
Valve literally spent years working with Linux developers on software that makes Linux gaming truly viable in order to create devices that allow you to run virtually any game on a handheld that you fully own, are allowed to put any game on (including games from other launchers, which they didn't have to allow) and you're fully allowed to self-repair it if any issues arise. Meanwhile, companies like ASUS and Lenovo treat their customers more like smartphone ~~suckers~~ customers, not to mention the fact that they went the cheap and easy route of just using Windows, which isn't optimized for a device like these. And guess what? Lenovo is bending the knee to the Steam Deck supremacy by allowing you to get a version with SteamOS in the future. That alone proves that Valve is one step ahead of their competition.
To summarize all that I said, the reason the Steam Deck is so good is not just the hardware, it's not just the screen, it's the fact that it's a very capable device at the hardware level, combined with very, very good software and a very consumer-friendly company behind it all.
Yeah, a lot of people don't seem to understand just how valuable our retro game collection can be. A lot of people think it's just about holding onto the past, but it's more than that. Not to mention the fact that the games you really loved for the consoles you really loved can hold very deep sentimental value that you shouldn't be forced to give up.
