Imagine if Linux was so unoptimized that it needed twice the CPU cores and RAM; your argument would be that "but it comes with twice as much as the other guys" and ends up being twice as expensive and twice as big.
The point is that the marginal value of that extra time is absolutely negligible for most people.
This machine will be my work luggable, I'm pretty sure it'll hold up all day.
First real run is tomorrow (dev+infra stuphz), I'll drop back in and let you know how it lasted if you're interested?
I love Linux as much as the best person but we really gotta get on that power thing.
This is the concept of diminishing marginal returns. You cannot look at "10 hours" in isolation; its value is lower when the baseline is higher.
It seems strange to argue that someone buying a workstation device should be okay with half the battery as a Windows user because it's Good Enough.
