I use both Linux and OS X. And one of the things that is sorely missing in OS X, is a decent app to take notes. Yes, I have looked around. Sidenote? Annoying and obtrusive. Mori? Complicated. Tinderbox? Doesn't look like an app I'm looking for. VoodooPad? Costs mucho money and looks too complicated. There just doesn't seem to be simple and straighforward tool for taking notes in OS X. Make that a _free_ app that is simple and straightforward. A zero-hassle app that just works. What am I using as a benchmark here? Tomboy. That is the kind of app I'm looking for. In Linux/GNOME it works like this: There's an icon in the taskbar. You click on it, and you get a menu with all your notes listed in there. Want to open an existing note? Just click on one of the existing notes. Want to create a new note? Just click on "Create a new Note". How do you save notes after you have typed them? Just close the editing-window, and they are automatically saved. It's so simple and un-obtrusive. It doesn't seem like rocket-science, yet such an app is sorely missing in OS X .
