I find the comment "for a sufficiently large input data set it will outperform 
most competing technologies" most interesting, and dated.

It beat competing technologies of the day, but not of today.

Consider that a fast card sorter could process about 2,000 cards a minute, or 
even if it could process 20,000 cards a minute, that works out to about 2,666 
bytes a second for the 2,000 card case or 26,666 bytes a second for the 
fictional 20,000 card case.

Syncsort MFX typically will process over 100,000,000 bytes per second, 
depending on the input and output devices as they tend to be the limiting 
factors.  CPU time may not be linear based on a number of factors, but I can 
buy more processors, I cannot buy more wall clock time.

The card sorter was the speed demon of its day, but it was replaced for a 
reason.

And it operates in time linear with respect to the size of the input data set, 
implying that for a sufficiently large input data set it will outperform most 
competing technologies.
