Well, OK, yes, I am sure that this is true. But, OTOH, it is an easy,
safe guideline, very easy to remember and to work out, and disk space
is very cheap these days. A gig or two here or there is nothing when
terabyte hard disks are becoming common.

I suppose the only time you would ever need even as much as 1.5×
physical RAM now on a modern PC is if you hibernated a machine which
was swapping very heavily.

But then, not everyone is running a modern machine. I have installed
Ubuntu (well, Lubuntu) onto 2 or 3 machines with 256MB RAM in the last
year or 2 and several with 512MB.
