I bought an older Android tablet (Galaxy Note) because I needed a light-weight device to take notes. It has an integrated pen for writing.

Also, there is MyScript Notes [0][1], which is an incredible app with text recognition, where you can add images and formulas and export your notes to PDF or LaTeX (even converting the formulas to LaTeX code). You can easily select and move, resize or copy/paste everything and it is quite fast on my tablet. You can also take pictures from the camera and paste them directly into the notebook, which is really neat.

I use it for everything I do, and thanks to text recognition, you can easily search all notebooks for specific keywords. There is a limited free version you can check out, paid is $2.

I am not affiliated with them, just enthusiastic about it.
