Duh, I didn't notice you can configure ThinkPads, might have gone that route if I knew. I ordered Lenovo Yoga Slim 7 Pro that is sadly limited to 16GB, but otherwise seems to be a huge success. High-res 90Hz 16:10 display, 5800H, good Linux support out of the box. I just hope the memory won't become a constraint. At least it was considerably cheaper than ThinkPads at 960€.
I considered this one but IMO not having dual-channel memory on such a super strong CPU is crippling it. :(
Plus yeah, 16GB is too small.
If it wasn't for that, it is IMO the perfect programmer laptop.
Got my device. It's super. A warning if any Linux user considers this though: Lenovo specs said Intel WiFi, but it came with Realtek 8852AE, and drivers for this aren't included yet in current kernels. It was straightforward to get it working with https://github.com/lwfinger/rtw89 (latest KDE Neon), but for the time being that will then have to be done after all kernel udpates.
