Notes writing leptop

Hi,
I'm a student and I want to buy a leptop that i could write on without any problems (such as hand wrist interfere while touching the screen).
I would like one with core i-5/i-7 fourth/fifth generation and 8 GB RAM (or 4 with an option to enlarge...)
Weight doesn't bother me, and so any other feature.
Which one should I buy?

thanks
