It’s only good if you have a massive battery, which means increased weight and size. I can get that same 6+ hours in a much smaller, cheaper package.
portability
I can see that.
That said, if the concern is only moving, a SFFPC can be very easy to pack. Monitors can be a pain, so if I knew I was going to move, I’d just sell those and buy new wherever I was moving. It’s just not worth the hassle unless they’re really nice.
It used to be more interesting back when LAN parties were a common thing, but AFAIK, most kids have moved to online. When I was younger, LAN parties had already switched to retro games w/o servers like OG Doom and Quake with mods, and those can run on a potato.
But honestly, my go-to is a highly portable laptop and a handheld gaming system, either a Switch or Steam Deck. That combo should be cheaper than a gaming laptop and more ergonomic. If you want to play games those systems can’t handle, a desktop PC + portable laptop should be competitive in price (like $1500-2000 combined), and should be cheaper long term.
That said, use what you have. I’m just saying that a Linux gaming laptop is kind of silly since it’s not going to handle many different games than a Steam Deck, and it’s going to be less comfortable to use than a more portable laptop and a handheld PC.
Obviously get what you want, I just don’t see much of a point these days when we have more options.
