I have used lastpass for about 7 months now and I love it. It is free to use and I never have to worry about keeping up with passwords. The built in password generator is also nice and it does the filling in of forms well too. I considered an online manager vs a locally stored manager and went with online because if hardware is stolen I can change the login password to lastpass and I am still protected.
Lastpass is also good at updating to support new browsers. It works for chrome, opera, IE and firefox. Even when betas for browsers are released they usually have a version out in a day.
