Unlike Evernote, OneNote doesn’t have any easy way of embedding web pages into your notes, which makes it a less-than-ideal tool for collecting info off the web for later collation and digestion. You can embed PDFs after a fashion, as “printouts” that can then be annotated. Files can be attached as well. Late last year, Microsoft added the ability to open notebooks stored on SharePoint Servers, as well. You can share notes with users outside your workflow by embedding the note in an email or by sending links; Microsoft offers the option of a read-only link or an editable link as well.
I don’t have any experience with the Windows version of OneNote, but I’ve read numerous complaints from users of both versions that suggest the Mac version comes up a bit short, especially in areas like saving text formatting options, document and file importing and attachment and more. As in all things, your mileage may vary in this regard.
It’s weird to think of Microsoft as underdog, but they really are when it comes to this kind of app. The 800 pound gorilla of the note taking app market is Evernote. To that end, Evernote has a better fleshed-out ecosystem of apps, accessories and tools to help you get the most out of it.
Interesting comparison between the 2 premier note talking apps – I personally will stick with Evernote as my workflow is too heavily invested in it but if I was on the look out for a decent note taking app, then I might be tempted to try OneNote.
