Hello, I trade the financial markets for a living so I look at the charts everyday. Right now I am using the Macbook Air and I was wondering if I upgraded to the Macbook Pro Retina would I be able to see more on my screen, browser, apps vs my current Macbook Air? Would there be a significant difference? This is how my Macbook Air screen looks currently. What difference would the Macbook Pro Retina make? Thank you.
