Now that I've been using 1Password for over a year (probably closer to two), it's become indispensable.
Although it's on the expensive side, I would say its worth every penny. 1Password can store all your passwords, as well as notes and other information like passport, bank account, credit card etcetera. It also has a password generator which I use every time I sign up to a new site/service. With 1Password on my phone, tablet, computer, and in my Dropbox, I have access to all my passwords and other important documents anywhere. They also make plugins for all major browsers that make using 1Password on your computer remarkably easy.
It has simplified a previously annoying part of my digital life, while also making it more secure.
Just set it up; works great!
