Michael Jennings ponders who pays who to include the trial versions of Norton AntiVirus on laptops. My guess is Norton supplies the software either gratis or at a low, lump-sum price.
I’m most unlikely to pay for an anti-virus subscription on my new laptop, as I have a virus scanner that processes all my mail anyway, and I really don’t download much software for Windows (except essential stuff like Adobe Reader and the like); I do most of my real work in Linux, and have done for going on a decade. If I see a Norton Utilities 2004 bundle (which includes an annual Norton Anti-Virus subscription) especially cheap at Costco, however, I might reconsider.
