There are ones with decent to good battery life. There are none with awesome battery life and abso-fucking-lutely none for super-awesome battery life.

That was one thing I never realized I needed until I had it. Having my laptop basically be optional to charge 99% of the time I use it changed my life. I can take it out with 20% left having not charged it in a week and still get a workday out of it. wtaf

Killer battery life is a defining feature of a laptop in my opinion, unless we’re talking hulking desktop replacement workstation laptops or something. Aside from physical attributes, nothing modulates portability like battery life does.

The user of a laptop with top tier battery life isn’t tethered to the wall, doesn’t need to care about availability of power outlets, and in many circumstances doesn’t even need to carry a charging cable and brick (or if they do, they can get by on trickle-charging with a tiny 15w phone brick overnight). This kind of laptop is in its own class of ultraportability.
