Update in case anybody is interested: I still love
Noteshelf and use it every day. I tried a few other handwritten note taking apps but this is the one I prefer, even if it lacks a few functionalities such as being able to bookmark pages or add typed content or vector shapes. It's simple and robust and I love how it looks.
I also bought
Notes Plus, which has lots of great exciting functionalities but feels more like a beta or even alpha than a stable and usable products. Plus it doesn't look as good as Noteshelf
Since I am in a spending mood, I'm also toying with the idea of getting
Notebooks for iPad which is supposed to handle many kinds of attachments, including MS office documents. The reviews are contrasted, it seems you either love it or hate it, so I'm still hesitating.
