*People* are different, and like different things. Men and women, however, aren't that different (roles in reproduction excepted), so a statistically significant difference points to a social or psychological cause, not biology.
That said, the PC isn't itself the problem, as the TFA -- or maybe just the summary -- seems to imply. Looking at other professions with gender imbalances, though, one can posit a few underlying causes. a) Secretaries were once men who helped important people with important matters; once the typewriter came in, women seized on typing as a "respectable" way to support themselves and the modern secretarial pool was born. (See http://www.stuffmomnevertoldyou.com/podcasts/why-is-secretary-the-most-common-job-for-women-in-the-u-s/) b) Blechley Park and earlier research projects employed female "computers" before they developed electric ones because women worked hard and worked cheap. All the mathematical whizzes, however, were upper-class men; who would pay for a woman's education, when they would just get married and pop out kids? (See also Disney animators.)
Obviously somebody needs to do solid research, but one could hypothesize that the PC coincided with three trends: the growth of male-dominated "hacker" culture, the use of PCs by Serious Men for Serious Business, and the decline of mainframes (i.e. server rooms in which nobody knew or cared women worked). Without hard data, though, this is mere conjecture. Loads better than "women don't like computers", though.
