I do use the same passwords for less important sites, where there are no financial data stored and I wouldn't care whether the site got hacked. There are just too many of those to use individual passwords for each. For Amazon, Google, Microsoft, PayPal, Adobe etc I use unique passwords.
And I actually use the analog method of storing passwords.
But then no other person has access to my things, I almost never have any visitors and I keep the password paper somewhat hidden, so an accidental burglar wouldn't find it easy to grab either. Not that I've ever been burglarized.
