I have just bought a brilliant pad. You can write on it with an ordinary pen or pencil, it uses no batteries or mains connector and the writing is permanent. It cost about a dollar so when it's full I can easily buy another one.
It's writing surface is called paper, dunno if it will catch on.![]()
Yeah those work great and are super reliable but I have a drawer full of them that I need to keep, so that I can reference them.
Anyways, I ended up purchasing the 4th generation iPad. IMHO none of the other tablets could keep up with the iPad. It was more expensive than most but I much as I detest spending $, it was the best choice. I also purchased the LifeProof case for it.
Now I need to find a good note taking app.
