Hello, I am needing a new portable laptop that I can take with me on my travelling. I have decided my choices are between the new Retina Macbook or the Dell XPS 13 which are similarly priced and can do my tasks very well. My default OS I would be using is Windows 10. I know the new Macbook is very capable of running, performing very well on Windows 10 and the hardware is amazing quality and compact. What machine has better battery life on Windows 10 and what would you recommend I get? Thank you.
