I use Keepass (or KeepassX, or KeepassDroid, and there's an iOS app too) and Dropbox.

Me too. Just remember to set the load-factor quite high. I've got it set to about 8 million rounds which is about one second on my beefy work computer, two on my private laptop and ~eight on my Android phone. The last bit is a bit annoying but at this point my key database is a pretty high value target - and I can't revoke access to it remotely if I lose my phone.

I'm very satisfied with 1Password..

I've been using Firefox Sync on my desktop and Android tablet. Unfortunately, I don't think the Firefox Home app on iOS does passwords.

lastpass should work.
