I've written before about the bogosity of the currently accepted practise of computing loss to piracy as "total store price of total number of downloaded songs/films". Kottke sums up the bogosity in a brilliant footnote:

[1] Well, [Sony's loss is] $10.50 if you live in Manhattan. If you live in rural Wisconsin, you're only cheating Sony out of $8.00 or so. Well, until the movie comes out on pay-per-view and it costs $3.95. But then when the DVD comes out, Sony's loss will shoot back to $26.99. Twelve months after the DVD release, when Bewitched is available in a value two-pack with Anchorman, Sony will only be losing $6. Whew, must be hard to keep all those losses straight.
