CintaNotes is an amazing application! It's simplicity is just what the doctor ordered. While Microsoft's OneNote provides the same and greater functionality than your app, it's learning curve is way too steep! That's where your product comes in.

If and iPhone/iPad application were offered, there is little doubt that I would be able to market your app to a minimum of 5000 users.

Without the application, they will certainly be sales opportunities but they will be greatly limited.
Obviously (LOL) please consider this a vote for an iPhone app
