Snapdragon X laptops with 16" or larger display yet? State of linux?

Got old eyes and a young mind. Curious to try something new, but tiny displays do not cut it for me. Are there any devices with a large display in the pipeline?

And I see Ubuntu is promoting their 24.10 Concept. Experiences? Battery life/power management? Wifi? USB/tablet/keyboard? Audio? Graphics? Are the device-trees reasonably complete?

Anyone tried running any kind of LLM on one?
