Need Some Advice on an Ultrabook

Hey all,

I have a cousin going of to college and needs some advice on a notebook choice. I recommended a 2013 Macbook Air or Lenovo Carbon X1 (as the desire for an ultra-book was high), but price is an issue. Our budget is 450-600, must have good battery life and adequate storage for a typical college student. Let me know what PCs are out there.

Requirements:

- Ultrabook/Ultra portable

-Good battery life

- Adequate Storage (128gb+)
