I just bought a new laptop, a lenovo t15g g2 laptop, and it took some hunting.  Normally I would not have considered Lenovo, but blame Stephen Partington for extolling the virtue of Lenovo thinkpads, and they actually are the beefiest boxes out there.

I never buy new, always used (like a car, let some sucker take the initial hit), usually Dell, and was looking to get base specs I need to the point I can upgrade to what I want.  It was a year or so of hunting to buy, I finally found one , this lenovo, around 2000 bucks with a base i7, 64gb of ram, rtx3080 video, and no touch screen.  I ripped out the 64gb with 4x 16gb for 4x 32gb sticks of ram for a full 128 I actually need/use, added 2x 1tb 980 pro samsung disks to the 1x 1tb samsung in it (an oem 980 gen sammy) for my os raid1 plus potential hot spare, and a lenovo tb4 dock that doesn't include that goddamn displaylink chip for video.  Still farting with it since I got all parts, but going to be Arch/KDE like my current box and watching it since last weekend with htop idling for issues.  Windoze was oddly randomly rebooting itself over a few days I was watching it for stability., but absolutely no issues since booting linux.  Meh, windoze shitting itself randomly is the norm.

Dell has great linux support, Mario Limoncello, one of the kernel devs works there, and tends to keep them in control to at least consider linux.  Lenovo is chinese crap probably I figure, but at least respect the need for power users based on thinkpad's legacy in their top-end, better or worse seems to still mostly hold it down.  Others - ymmv, less than more mostly.  Hopefully the lenovo bios isn't creating a backdoor vnc to my desktop perpetually found on shodan.
