This argument is not valid. While most parts of a computer got faster
things are not growing at the same rate. So what might have made sense a
few years ago might be completely useless now.

One thing that makes deltarpm less useful nowadays are seek times in
hard disks (although they are going away). They are still the same as in
the nineties  while the number of files have been growing.

At the same time network bandwidth has been growing at a faster rate as
everything else.

So if you want to make an argument for deltarpm, please do so but do not
try to convince us to buy into an outdated rational.
