Just helped my ex choose a new MacBook Air to replace the 2013 4gb/128gb MBA she's had since 2014. She still had about 25gb free space on the 128gb SSD and thinks she'll actually be storing less as she is semi-retired now. So, we went with the base 16gb/256gb version. Of course, her needs couldn't be more different from mine but I suspect there could be a lot of others out there like her.
