Actually I do use variations of similar passwords too. And some are written in an oddly named folder in my document folder, and in a little notebook, as well as another notebook we keep in our safe.
Ive not got anything to protect except our banking sites and the mutual fund and brokerage site stuff, but its more for me, if I forget them or want to change something.
Its a nuisance, but if anybody ever stole one of my computers, it would indeed be protection. One of our kids did have a laptop stolen, but had no sensitive info on it.
This is an interesting topic.
