They sadly advertise with an “AI” part, which, ew. But they seem good other than that.
That's just what AMD calls their latest laptop CPU line. I don't like the name either, but performance-wise they look really good from what I've seen.
are all of these laptops customisable in terms of OS?
I haven't bought any of these laptops so far, I just looked into them because I was considering it. That said, all of them offer various Linux distros, Windows, or no OS at all. I don't see why you wouldn't be able to install whatever you want on them.
As for security I'm really not the person to ask. The way I see it, a computer is as secure as you make it. StarLabs shipping with coreboot out of the box does seem interesting though, if you want to go full tinfoil hat :)
I can't even find a single positive comment on YouTube. Maybe there is still some hope for the games industry, when absolutely everyone is starting to reject the Gatcha/GaaS/MTX slopware.
