I own an RTX Spark laptop, and it's not the one I grab when I want to run local AI. That job goes to the Asus Zenbook A16, a Snapdragon X2 Elite Extreme machine with 48GB of RAM that costs about half as much as my 32GB OmniBook Ultra 16. It's not the faster of the two, but it loads the models the RTX Spark won't, it weighs barely more than half as much, and it's the laptop I'd tell most people to look at first.
