What's the difference from Chromium? Main "selling" point?
Company responsible for one of the most played games on the planet unable to pay its workers. Feels like someone at Epic is horribly irresponsible with finances, or just maybe infinite growth is impossible and harms everyone below the execs.
Not to mention the community controls are great. Larin did a fantastic job adapting the game to a controller, but I much prefer the flexibility of keyboard and mouse and the Deck's input options are fantastic.
Let's not forget to mention the Steam Deck's low price for pretty great PC gaming. Even more so for the refurbished entry models which are nearly the same price as the last GPU I recommended to someone (secondhand 6700 XT). I've been surprised how good of an experience I've had with Baldur's Gate 3 on the Deck.
"We have too because it's just SO expensive to make video games and we're just struggling companies." Nintendo said while lighting a cigar with another $100 bill.
While I will always mention how much I love my Steam Deck, I will say having a console you can buy physical discs secondhand is quite nice. Sure the PS5 is a lot of power just to run something like Bugsnax, but I can't buy a physical copy for my Steam Deck, which I know I really own.
You could even go into a retro game store and see what you walk away with, games you never heard of or just a stack of cheap former AAA games. You could also go on Itch.io and just poke around for any obscure indie that sparks your interest. Once you get away from the glitz and glamour of AAA hype, you'll get excited about sharing games people haven't heard about or discovering something you wouldn't find walking into a GameStop.
Meanwhile I will be wearing my pink "Bad Guy" Vegeta shirt and cracking jokes with my friends AFTER the movie, like a true American.
The SD card speeds are great. The only thing you need to keep in mind is when you're doing something that requires managing file paths and isn't designed specifically for the Steam Deck. I ran into some headaches figuring out how to install the Vortex Mod Manager and get it fully functional for modding Skyrim on my Steam Deck's SD card. I'm sure things have improved since then, but for people new to Linux it can be a slight hurdle if they choose to go outside the scope of typical Deck stuff.
I did try building a HTPC in the past, but it was just a headache to maintain. If didn't use it for a few days, I found I was inundated by a bevy of updates. Kodi is a pretty powerful home theater software, but definitely not as simple as launching a Netflix app. My partner also had no idea how to operate it. Personally I prefer Moonlight streaming from my PC in my office. Once I get an ethernet port installed in the living room, it'll have great picture quality and latency. Your build does sound pretty cool though.
I have hear not great things about the ROG Ally and its support from Asus. From my experience, the Steam Deck truly is the most pick up and play solution for PC gaming. Add in the best input options of any console (people complain about the trackpads making the Deck too big, but those people clearly haven't used them) and I think it beats out a gaming laptop as a gaming device. If you're proficient at minor disassembly and formatting an internal drive, you can pick up the base Steam Deck for $399 and then buy a 1TB-2TB drive for less than what the 512GB model would cost. Alternatively you can buy a 1TB if you don't want to open the device up.
Me personally, my go-to console at this point is the Steam Deck for its sheer versatility. I've got a dock with an 8Bitdo Ultimate Pro connected so it's more or less plug and play. Since building my first PC in high school, I have a huge Steam library. EmuDeck is also amazing so with the exception of a Series X somehow running emulators, the Steam Deck is the best console for emulation.
I've had an Xbox One S as my 4K blu-ray player and have been digging the backwards compatibility, though there's not enough OG Xbox support. I'm more than likely going to mod an OG Xbox with the Stellar chip/HD mod. I've considered a Series X, but unless it can replace my Nvidia Shield TV as an entertainment box, I'll probably stick to my Onse S. I've also considered a PS5, but their games are coming to PC, albeit delayed, so I don't really feel the need to pick one up.
The PS3 is a special beast as those games are seemingly trapped on the console unless ported (RIP Beenox Spider-Man games). When modded you have the ability to software emulate PS2 games (not as good at the launch PS3 but those things won't last), but for me my TV still has a component connection so my cheat is having a PS2.
Nintendo has one of the most beloved library of games, but the Switch does not support much of said library unfortunately. The Wii U on the other hand had better compatibility especially if you modded in GameCube support which runs natively on the console.
The only thing I can't get working on Sunshine on Wayland is a visible mouse cursor. Makes streaming Baldur's Gate 3 with a cursor a pain.
