Hey guys, I want to purchase a laptop. I'm looking for the following things: long battery life (6+ hours) i3 or i5 processor 4GB ram video card that can do CAD 14-15" screen 6lb max I am an engineering student that mostly uses the internet and writes lab reports. I won't be doing any gaming on it. I looked at an Apple 13" Macbook Pro, but I wasn't impressed. I need some help choosing a reliable brand. My maximum spending limit is $1200. Thanks!
