Re: "256 is a bare minimum ..., just enough for the OS to run reliably",
while I agree that 256 is a minimum if buying a new machine, xp will
load and run in 64 megs with some limits on functionality and slow
speed, and much better with 128 megs. There are tons of older machines
that can only be expanded to between 128 and 192 megs of RAM but that
are otherwise capable of running XP, and it's not always unreasonable to
do so.
