A different kind of note-taking software

In struggling with organizing my piles and piles of research notes, I find this small software called "evernote". Unlike many other software of its kind, it does not force to think ahead to assign a category before you begin a new note; instead, it is like an endless roll of paper on which you can put anything without much thinking and planning; then you can put a list of keywords and let the software to do the manual job (searching and indexing) for you.

Here is the software: http://www.evernote.com/en/
