Only unique passwords for important sites? For shame sir.
Mind you, I use lastpass to generate unique passwords for each site - my memory is not that good.
I'm always reticent to trust a 3rd party with my passwords, particularly when they want to sync them with the cloud (although I can see how that is a requirement for convenience sake...). Currently I only use the password managers in Firefox and Opera, encrypting the password store in both with a master password.
That said this inconvenience may be incentive enough for me to switch to something like lastpass.
