Hello everyone. I'm currently using a 2010 macbook pro 15' with an ssd and 8 gigs of ram. The computer still works absolutely great for all my needs apart from an occasional issue where the screen flickers green but it rarely lasts longer than 5 minutes. I've been thinking about upgrading to a new laptop for a long time but am having a hard time deciding what to get. I am a medical student so most of my time is spent doing schoolwork. I also develop web applications as a hobby. I've thought about upgrading to the 13' rMBP (refurb or non-refurb.. doesn't really matter much) or possibly a 13' macbook air for the exceptional battery life. I've also thought about getting one of the excellent windows laptops out there like the xps 13 by dell; however, i don't think i can stomach using windows again so thats most likely out of the equation. I'm not looking to spend a ton of money.. preferably under $1200-1300 although i am willing to spend more to future proof the machine. Do you guys recommend i buy any of the machines i listed above? Or should i wait until the end of the year and get a broadwell based macbook?
