This is a very interesting read.  I do not believe these noted issues should warrant the abandonment of password management tools.  As the author states, much of the security concern lies in whether or not you consider your workstation secure and trusted.  Password managers in combination with multi-factor authentication mechanisms is a sound and strong approach to credentials management.
