/v/irgins help, do i buy a steam deck

So here's the sitch:

• I principally vidya on my desktop PC

• When practical, I use an xboner controller so I can game from any room (my pc screen is mirrored to all TVs in the house)

• I only play single player games, mostly normie stuff like Fallout, BioShock, Elder Scrolls, etc

• I have a laptop with okay specs, AMD 8700P or similar. It could run BioShock Infinite all the way through the story, but it wasn't happy about it. It's been getting laggy about even watching fullscreen YouTube, possibly due to thermals. Fresh reinstall of Windows didn't fix it.

• I'm on the road for work for a couple months. I don't like to travel, but sometimes it's either this or be on layoff

• I also take one or two vacations annually, usually flying.

I'm home every weekend for the duration of this project, so it's not really practical to bring my desktop PC to the hotels.

My laptop can't handle my current fixation, shapez 2, unless I really throttle down the visuals to bare minimum. I'm kinda reaching my endpoint in that game anyway.

I can't decide if I get a used gaming laptop (2-3 years old) or a Steam Deck. I don't play the latest and greatests -- the newest AAA I have is red dead 2.

My laptop feels a bit dated but I like the big 17" screen, and it still gets a bit clunky trying to use it in a hotel room -- especially with this week-to-week where I'm not going to bother hooking up to the TV.

I see there's a 512GB OLED model for $450 near me, brand new.

But, I don't REALLY know if it's worth it to me. I can afford it, no doubt, but I need to JUSTIFY it. Even though I could always sell it if I end up not liking it.

I also looked at the Asus thing, everyone says the Windows is better for modding, battery life is DOGSHIT.
