Out of all the note-taking applications that are available for OS X & the iPhone, I have to say that this one has come the nearest to meeting my fast-paced environment. All-in-all, this is a very lightweight and functional little app that does all it was meant to do: take notes... But there are a few things that should emphasized about this particular application.
If you are ever in a hurry and you're reading an email, you'll sometimes realize that you missed something of great importance or you skimmed through a section that contained the point of the monstrosity that is a weekly report... It's always nice to be able to extract little tidbits for later use, and that's where this app conquers all others in functionality. Needless to say, the iPhone synchronization makes this app killer for on-the-go extractions from the computer for later use, or vice-versa.
This is not a to-do app, but it can serve the purpose quite nicely, as long as you don't plan a project within it. (That's not the function of this application, nor was it intended so.) For notes, it's far superior to any "premium" or "full-featured" application due to it's condensed size and huge functionality within the field of "note-taking", but it may not fit everyone's needs.
Since it's free, why not give it a try? If you don't like it, toss it. It's that simple!
A+ for the functionality and lightweight environment! This is perfect for the fast-paced lifestyle such as mine!
