I don't think anyone that dismisses this really understands this. I've never had a laptop that could for more than about 3-4 hours doing dev work, but in 2014 I could get 8 hours of dev time out of an Air, and I can do that now on my M1 Macbook Pro.

For someone who is actually out and about all the time, this is life changing.

If you just sit with your laptop tethered at your desk all day, they why would you ever care?
