I'm using my steam deck right now as a gaming PC while moving across America.

It works really well. I got a dock from Amazon that gives me the ports to plug in my gaming mouse and keyboard. I can do HDMI out to the hotel TV or, better yet, lead out one USB-c cord to a fantastic portable monitor.

I only ran into two minor issues. The first is getting enough juice to the steam deck and heat. Both can be easily solved with a good fast charging station and better air flow (I use this tiny hyper fan and have had zero issues in 90 degree Florida winter weather).

Of note, I dual boot with Windows 11. It's a bloated mess of an operating system, but I want to use certain mods and programs that windows only. Plus, I'm not tied down to only steam games. The addition of being able to run nearly everything that's Windows compatible takes the deck up a level, I feel.

The best way to get the most out of the Windows environment is to run a debloater admin tool, which removes unnecessary programs on Windows 10+ systems. The difference between the performance is shocking, making it pretty much required for usage. It's not too hard to use, too.

The best part of it all is that you still have a stream deck at the end of the day. You don't have to do any hardware mods. You can pick the deck up and walk out of the house and still have the gaming PC with you.
