  I think it's anything but surprising. There's only so much you can do to
  significantly improve systems security if you're unwilling to break
  backwards compatibility -- many of the fundamental premises of desktop
  security are fatally flawed, chief among them the idea that all programs
  execute with the full privileges of the executing user.

  One Laptop per Child is breaking application backwards compatibility for
  a number of reasons, one of which is security. As a result, I'm
  earnestly hoping that our systems security platform, Bitfrost[0], will
  be an improvement on the scale you're talking about. But time will tell.

  (Sidenote: I'm giving a keynote at AusCERT tomorrow about exactly this,
  titled 'Everything you know about desktop security is wrong, or: How I
  Learned to Stop Worrying and Love the Virtual Machine'. Any list members
  who are at the conference should mail me if they want to play with an
  OLPC laptop and commiserate about desktop security over beer.)
