We've been fans of Amazon's very cheap S3 storage ever since its release, but they've just announced that they're adding a free tier to their pricing plan — so there's no reason not to grab 5GB of free storage right now.
Whether you're using Cyberduck's great S3 integration, hosting your iTunes library, or just backing up your system online, Amazon S3 has some pretty great uses. Until now, it was incredibly cheap but not free. For the next year, though, you can get 5GB of free S3 storage, along with a ton of other free features from Amazon's Web Services, including EC2 Linux Micro Instance usage, Elastic Load Balancer and Block Storage and more. Even if you don't need things like a virtual Linux environment running for you 24/7 on Amazon's servers, the 5GB of free storage is easily worth the quick sign-up. The year of free service starts on November 1, but you can sign up right now, so hit the link if you're interested.
