So I am a sophomore Astronomy and Physics student looking for a powerful laptop to do programming and to help me with research. I would like it to support things like Python, MATlab, LaTeX, Mathematica, LabVIEW, anything for astronomy, but relatively lightweight and has HDMI, Blu-Ray, high resolution. I liked what I read about the Dell xps 15 but I would like your help. I AM a college student so somewhat cheap is good... nothing more that $2000. That is still a lot but when you need the right stuff... Anyways, thank you for your help!
