Which Ultrabook for College?

Not sure out of the Samsung Series 9, Zenbook Prime, and X1 Carbon. They all seem really good except each one has it's own issue. The Samsung only has 128gb storage, is that enough for a college laptop? The Zenbook looks a bit too flashy and also has a huge bezel, but has all the specs. The X1 carbon has some great features, like a great keyboard and a trackpoint (makes precise actions like word documents much easier), but I have not heard great things about Lenovo's quality control recently. My brother has to manually kickstart the fan on his, my father's needed a new mobo, and several of his graduate students are also having problems with theirs. Any ideas?
