A nice illustration in the perils of extrapolation. Per the formula,
hard drives should be $0.006 per gigabyte now. I don't see anything on
newegg.com for less than $0.03 per gigabyte; the best deals appear to
be at the 2 TB level. And we're only 4 years out of the data range.

It also seems odd to quantify technical advancement in a way that is
easily affected by fluctuations in the strength of the US dollar.
