Suggestions for a tablet for taking notes

Hi

I was looking for a tablet to take notes to replace the old school pen and paper. What would be the best option in this case? I just need something with a pen and a decent notes app which allows me to draw straight lines and use different colors (Civil Engineering student). Probably I’ll also use it for media consumption, but not that much. Also, good battery life is a must as I have to be at university for 8-10 hour per day and I would prefer a good quality, high resolution screen. I was looking into the Apple products, but if you have any other suggestions, I’m happy to check them out.
