Well those are virtual notebooks. Notebooks usually don't have a fine structure, they are not good for particular data but they're enough good for almost anything that you would like to record. Another point is that those are usually synched, filesystems usually are not, except Dropbox etc. Usually I use Evernote to collect some ideas or articles that I want to read or think again later. I wont use bookmarks(or delicious) since it's hard to recall from title/tags. I won't print them since I have no printer and don't want anymore paper. I won't save them to my disk since its not synched across devices and it's still PITA to open all the files separately. Also I want to record some automatic metadata and not to input all myself.
