I run my GTD system through PersonalBrain and use Dropbox to sync that between my work PC, home laptop and my wife's PC (for backup and sometimes more convenient access). Sometimes there is a copy on my USB stick as well.
So that makes four at most. Why only four? Because I don't keep a copy in my head!
And that's GTD.
