At the risk of belabouring the obvious:

   i) I like the price.  Free.

  ii) I like the operating environment -- CLIs aren't to everyone's taste,
      but I find they give me the freedom to do what I want without having
      to jump through a whole lot of hoops.

 iii) I like the efficiency of the OS -- you get that much more performance
      out of every machine it's like having additional servers for free.

I thought you were pillorying synthetic benchmarks upthread?  Filling up
a partition with a file of zeros is pretty unlikely as a real-world task.

I wouldn't be too disappointed if that didn't run as fast as it possibly
could, although I would be distinctly peeved if doing that on a loaded
server took up more of the system resources than it had any right or
justification to do, to the detriment of anything else running on that
