The Lenovo Yoga Book bridges the gap between tablet and laptop, and is designed to make taking notes, drawing, and pen input easy. The biggest difference between it and a regular laptop is it's lack of a dedicated keyboard. Instead, the entire surface is touch sensitive and you can enable the keyboard, or disable it for full use with a pen (you can even take notes with a traditional pen on paper on top of the touch surface, and it will add it on-screen as well.
