People without this particular 12 hour battery life requirement (which is quite niche, most of us live near plugs) are talking about what works for them.
Ok, perhaps it is not niche. I don’t know. I have never had to use a laptop for 12 hours without any ability to recharge but if that’s a common use case I’m happy that folks are finding a way to satisfy.
But when I can go for days on my work Macbook without charging (and I am a developer, so I do compile stuff), I kinda wish I could have that on Linux, too.
And again, I don't need it. Just like I don't need a fast Internet connection, but well... :-).
