I don't really see the point of having 1Password on anything but your phone (unless you don't have a smart phone). It seems like the most secure way to use it, assuming you've enabled back ups in 1Password to iCloud or DropBox. Whenever I need a password I just grab my phone and look it up, then type it in. Sure, I have to manually type passwords, and my randomized passwords all have a minimum 18 character length, so…
Passwords are terrible. 1Password and related software make having to live with them significantly less terrible.
