Ah, but the relevant unit here is person-hours, not hours: Jobs is claiming that *each* Mac user loses X% of *their* life to boot times, and then adds all those slices of life together into N lifetimes (which again, are counted in person-years, not years). It's still wrong, though: longer boot times actually increase the proportion of your life spent in meaningful activity (e.g. going to the canteen and talking to someone). -[]z. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
