Franework is nice but no Nvidia option which is a no-go for LLM.
Thinkpad P1 Gen 6 with RTX 4090 is a solid one. Older generation but Thinkpad seems like no longer slapping top GPU into its notebook.
Other laptops with 4090/5090 are too huge (Titan, Raider, Vector, Strix Scar 18,…)
I’m using Arch on the Thinkpad above.
Hope this helps
