The original article is confusing. Boot Camp is of course free, but only permits rebooting a Mac into Windows. For $70 one could purchase VMware Fusion or Parallels Desktop, and run Windows side by side with OS X. The author of the Washington Post piece does not make this clear. Calling Boot Camp a "secret weapon" suggests that most people aren't aware that Apple computers can run Windows. This may be true in the wider world, although any Apple employee in a retail store could inform customers otherwise. Expecting a writer not focused on technology to discuss gratis tools like VirtualBox and modern.ie is probably asking too much (although these would be well within the reach of Hacker News readers).
