I know, and I don't like the fact that it uses .NET either.. Especially because it doesn't use plain .NET but GTK as well. It's a bit of a hassle installing, even on Windows systems that come with .NET but not GTK.

However its performance is amazing, it's the fastest notetaking app I've ever used. And I also really loved the lack of the concept of 'saving'. Everything you type is automatically saved.
