Apps like this are funny. Looking through the comments now, it's as if every one of us has implemented one of these (yes, I have too.) One simple explanation is that they're easy to write, and fill a need we all have. I suspect another reason is that as developers, we notice a problem: "I hate taking notes!" and then instinctively, we try to solve that problem with technology: "I will write a better note-taking app!" I have no strong feelings about this variant, except that I really think it should size itself to my browser (with a reasonable max-width.) That would make it pretty multi-device friendly (mobile/desktop/tablet), and be basically 0 work on your part.
