Amazon's drive offering is particularly attractive if you're looking for a way to store your music library. They recently added Safari support, so if you're on an iPhone or iPad you can now use the service. If you're already set up with a Cloud Drive account, and have some music in it, just point Safari to the Cloud Player sign in page and you'll see the desktop interface on your iOS device. Sign into your account and you'll see the desktop interface on your iOS device.

On the downside, there's no sync service or automated way to add your non-music files. It's all manual upload and download. This is a fair place to hold your music library, but not useful for much else, given the options available today. Also, being forced to manually upload files via a Web browser gives the product a rushed and unfinished feel. However, it's hard to complain about a free place to store your music. If you're looking for a good place to store and stream your music library and can use some rudimentary non-music file storage as well, then Amazon Cloud Drive may work for you.
