I just started using LastPass today and I gotta say it's proving to be better than keeping all my passwords in a TrueCrypt volume. Was leery at first about my data being stored on their servers but I've read up on it and its reputation and safety is solid. It just makes using passwords easier; gotta remember to not leave LastPass running if I leave my laptop. It'd be like leaving my TrueCrypt volume mounted.:(
You can actually get much the same functionality from KeePass (with the KeeForm plugin) but LastPass is a wee bit more efficient.
