Should they > include information that helps track what computers I use? Uh, if I were young, slim, and sexy I really wouldn't want my stalkers to know when I plan to walk alone in Central Park, or when I'm going anywhere for that matter. And I would certainly give that concern priority over them knowing whether I made a particular appointment via my iPhone or Barrack Obama's PC. Oops, you're not supposed to know I have access to that, I guess it would be scary if that leaked. Yeah, right. No, they shouldn't include that information if it can easily be avoided. But get real. When Emacs net apps all route via TOR only by default, then I'll concede you have a point.
