With Evernote having a tough time of it lately, Microsoft is trying to swoop in with OneNote. It's just released the OneNote Importer tool that will make it easy for folks to transfer all their Evernote data to its own ecosystem. To use it, you'll need a PC with at least Windows 7 installed (and preferably Evernote for Windows), so it's not an option for mobile or Mac-only users, at least for now. If you have multiple devices, however, any notes you import will be synced on Mac, Android and iOS.
