Rated 5 out of 5 stars
I've only been using this for a couple of days, but so far is great! I still use xmarks for bookmark sync, but xmarks does not support password sync for anything but Firefox. LastPass features are also far superior as far as passwords are concerned.
Anyway, this imported my KeepassX passwords in no time, and has solved my Windows 7 / Ubuntu 10.04 password nightmare. Thanks!
