RoboForm - Bookmark/Password manager

Well I started using RoboForm a couple of days ago after reading the comments on Dan's post. So far I have to say I really like it. It fills in form data. It acts as a bookmark manager and if that bookmark needs login information then it will fill in that information and login so you don't have to login every time you visit that page. Another feature I like is that all the bookmarks (passcards as they call them) show up in both Firefox and IE. I'm almost thinking of using this as my standard bookmark manager as well as my password database. For security it has a master password so I only need to remember that one password. Also if I want more security I could store my data on a USB key drive.

We'll see how things go, I'm going to continue using it for a while to see if it meets my needs. Does anyone else use this or know of any problems with it?
