My 27 DS uses his iPad for nearly every class. When we visited for Family weekend, and PPW, we went to a class with him (which I highly recommend doing to see what UMSA classes are like) and both times, he pulled it out for notes, classwork, etc. Over the Christmas break, my DS and I build him a small PC (called a mini-ITX) for doing things that are just out of the laptops reach like CAD (he is majoring in Mechanical Engineering) and a bit of entertainment. The reason for being small, it has to be packed away for the summer.
