What should I give my girlfriend for university?

Soon my girlfriend is going to university and I wanted to give a little present. I've noticed that it's not that well-equipped and you should have a laptop or tablet these days. Please take part in the survey and explain your decision. What she does with it is not that important as she will just do things that normal students do.

Or alternatively a good, used Lenovo ThinkPad, but from the dealer.

Laptop + tablet / iPad (so you can, for example, follow an online lecture on the laptop and take notes on the iPad / tablet)
