What are some christmas presents that would benefit a college student?

I have an uncle to insists that he gets me a present for christmas even though I have all that I really need. I know my sister is receiving a new laptop, so I was thinking about asking for some type of electronic that would aid me in my studies. I have a macbook pro, is it possible that I get a desktop screen that I can connect to my laptop and use as if it were a computer? Any other suggestions?
