I would agree in general for the base model macbook airs, as you go up the range the value just isn't there anymore when in comparison. I still do not see the battery life for my use case. There are too many other flaws for me (repairibility, quality of software decreasing massively, issues with screen quality in everyway bar colour/vibrancy) though that means I won't choose them anymore as much as I adored Apple for many years and am still a fan boy over classic macs.
