Livedrive goes live (online storage and backup)
You can certainly find cheaper online backup solutions (Mozy and Carbonite come to mind). But Livedrive offers a few features that you won't find from other services, including integration with Windows Explorer and social features like Facebook integration. And once your files are uploaded to Livedrive's servers, you can access them from any computer with a web browser.
If you signed up during the beta, Livedrive is offering a 20% discount to the first 10,000 beta testers who sign up for paid accounts.
