The argument is valid because the original PC was shipped with one row
of 16Kx1's soldered in.  Later, when OS requirements changed, the
sockets were filled to 32K, 48K and *even* 64K of 16K chips! :-)

The same argument influences the design of the 32 bit PC's today.
256Kx1 chips are very popular for "entry-level" machines.  One
row of 256K's is of course 1 Meg, which is "perfect" for an AT-style
architecture.
