Lithium ion batteries are far cheaper now at a consumer level than they were thirty years back.
EDIT: I’m actually surprised that a higher proportion of laptops today don’t ship with 100 Wh batteries. Go back some years, and shrinking the battery had a much larger difference in cost than it does today. The larger battery gives you longer battery longevity (makes it more reasonable to charge to 80%, say), can be used to make a laptop run more quickly, can power more devices. The only drawback is weight, and it isn’t that heavy.
But the savings haven’t flowed down to us. Gotta make line go up, it seems.
