>Who's out here using their laptops for 18 hours continuously?

"We should stop battery improvements because no one I know uses it" (to put it with a bit exaggeration) is certainly a novel take. Sometimes I put my laptop on the kitchen counter after doing stuff and not have to worry it'll be dead next afternoon when I need it for something.

You're forgetting one important take. Batteries degrade. In 3 years your "10 hour battery" will be more like 3 hours.
