I can only answer how I use it, but here it is. I take notes. Those notes sync to my work and home PC's my phone, my iPad and are available in a web app. Those note can contain images and rich formatting such as tables. I also keep my todo list in it, as notes can contain check boxes. I keep my notes in hierarchical "Notebooks" (folders). Finally I can search through all my notes. All of the above make it a really excellent note app, not quite as good as OneNote but the syncing in Evernote is vastly better then OneNote's. I know that other people scan documents into it, and that Evernote will OCR hand writing and make it searchable but that isn't my use case. You can also send emails, PDFs etc to it but once more I don't use this.
