Evernote is more than an online storage service; it allows you to organize, tag and share notes and files between just about every platform (Mac, PC, Web browser, Android and iOS). But as an online storage service, it’s pretty nice, too. Rather than measuring your usage by volume, it provides you with 60 MB of free upload bandwidth per month, with additional "premium" bandwidth limits at a fee. What’s more, a number of other technology providers (printer vendor Lexmark, for example) are now supporting the Evernote platform in their products. It's available as a Web application, a PC application, a Mac OS X application, on Android and on iOS.
