For me, though, the excellent interface and features of CintaNotes work better than any of the other apps. It is snappy, beautiful and the functionality is just right. It also handles the tag based approach for managing notes perfectly well.
What's cool about it is your note is recorded with meta inf, so it keeps a record of the web address where you took the text from, for example. That means I can stick anything interesting in CintaNotes, find it again without problems (did I mention the search is great?), and work with a more manageable number of browser tabs and windows! Once my morning delving is done, I just put it all in CintaNotes. Now my desktop has a zen-like calm about it.
