I was told a few years ago by a smart person I respect that one of the
reasons Mac laptops were still so poorly endowed with RAM (iirc 8 GB
max) was because Apple was shipping SSD in them, so the performance hit
wasn't really noticeable.  One hopes those were sturdy (DWPD) SSDs, but
barring the marketing decisions (removing ports people want), Apple's
hardware engineering is usually decent.
