Another vote for eWallet. Very flexible, although it doesn't fill forms, but that's fine, since I use a variety of browsers (Opera, Firefox, Seamonkey...) and they all do things differently.
The main thing for me is that it is extremely secure, unlike the browser password managers, and I can use it on both Palm and Windows. Stuff that I don't care about much, I leave in the browser's manager. Anything that could cost me $$ if it escaped, I keep in eWallet only.
eWallet is also useful for keeping other kinds of information than just passwords.
