A non-operating system

I enjoyed this letter in the latest issue of The Economist:

SIR – I found it ironic that you concluded an article on noise- cancelling technology by referring to a new microphone from Microsoft that should ensure “there is no longer any reason for people to shout at their computers” (“Opting for the quiet life”, February 13th). Anyone using Microsoft Windows has every good reason to shout at his computer, and frequently.

Indeed. The Microsoft operating system on my PC does provide one benefit: it gives me plenty of opportunities to exercise my primal scream therapy.
