Keep in mind the Ultra 300 chips also only have recent support in the kernel. The battery life likely isn't great for now (as with previous gen Intels right after release).
It makes sense to me that for now the benchmarks would be Windows specific.
battery life for Linux is not some grand project, it's just support and setup of existing kernel drivers, typically at the distro level - which is why it's already there for some setups
This is essentially why I'm confused. All he's doing is setting up pre-existing drivers, any chimp with access to ChatGPT can do that.
I don't see that he's bringing anything noteworthy to the table, but I've repeatedly heard people talk as though he's going to bring better battery life to Linux through omarchy.
