I had a crappy PC so I got a Steam Deck at the beginning of the year. I was recently able to get a fancy desktop rig that can run pretty much anything on Super-Ultra RTX-On Turbo Mode, but still find myself using my Steam Deck quite regularly. My Steam Deck is my goto most of the time as I just enjoy chilling on the couch or in bed with a game.
So yeah, I think both systems have their uses and its not weird to still use the Deck despite having a beefy desktop rig. I also love being able to take my games with me on the go. A visit to the DMV isn’t so terrifying anymore.
Don’t forget about desktop mode. You have a full computer there. For a while it was my main computer. It’s Linux, but that isn’t been a huge issue for me. It’s generally easier to download programs as you can find most of what you need by searching on the discover app and downloading directly from there.
Decky Loader is awesome. It gives you access to a lot of little tweaks themes and other cool and useful stuff for gaming mode.
Steam Input is amazing. It lets you remap every button to whatever you want it to be. There are a number of games that I didn’t think would be good experiences on the Deck that were absolutely amazing once I to advantage of the extra back buttons and trackpads. Many people have uploaded their own controller profiles so you often don’t even have to do it yourself.
Lastly, don’t forget to actually install and play games.
