> not supporting over 16 gigs of LPDDR4 RAM The limitation is actually 16GB of of LPDDR3. Intel Skylake CPUs support up to 128GB of unbuffered DDR4, depending upon chipset, and don't support LPDDR4 at all at present. Apple chose to use the older, lower-power RAM specification and thus adopted the limitation. If they'd left the battery capacity unchanged then perhaps they could have used DDR4 but apparently their priority was reduced overall volume.
