There are other note taking apps out there, but I have always found they are just "yet another thing" to do, instead of making my life easier. My desktop is maybe chaotic, but it works. CintaNotes, however, feels natural and sits in the system tray ready to spring into action whenever you need it: highlight text, hot key, you're done. Easy.
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.
