Being on OS X, I have moved to 1Password. I'm, to this day, a dedicated proponent of Keepass. Anyone, asking me to suggest a Password Manager - my first answer is Keepass (Windows or Linux). Even for OS X, if one cannot afford 1Password yet or do not want to buy it just yet, Keepass is the one.

* Spend some time learning the Keyboard shortcuts and you're all set.

* Keep the Keepass File on Dropbox, so it's sync across your machines and is backed up.

* Sharing common credentials with a team - server login details, team site details etc - have a common Keepass File on Dropbox and share it with your team. Suggestion is to open it as "read-only" unless you're adding new entries.

* You can also have an additional layer of security by using an additional (optional) Key Locker File (besides the main password) to lock Keepass. You can have that on a thumb-drive or some place you know.

* One thing I really wish 1Password has what Keepass has is the auto-generation a password when you enter a new entry. One can set parameters of what password is generated. I have click to get that in 1Password.

P.S. If I remember correctly, Keepass even has a portable version.
