I use KeePass and like it well enough. I able to synch the password file between my desktop, laptop and phone. Really makes it handy and since I have copies in different physical locations it serves pretty decent as a backup solution too. My only real issue that I switched to Win8 phone a few months ago. There is no version of KeePass available yet for windows phone. There is a password vault application that looks very similar to KeePass and will synch to your SkyDrive. This looks pretty cool but then I can't access it without my phone.
