That's weird - if software gets 2x worse every time hardware gets 2x better, why did my laptop in 2010 last 2 hours on battery while the current one lasts 16 doing much more complex tasks for me?
Elsewhere in the comments, it is noted Apple's own estimates are identical despite allegedly 2x better hardware.
Aside, 2 hours is very low even for 2010. There's a strongly usability advantage for going to 16. But going from 16 to 128 won't add as much. The natural course of things is to converge on a decent enough number and 'spend' the rest on more complex software, a lighter laptop etc.
