I've always been a PC user but now that I need a new laptop I'm going to switch over and try out a MacBook Pro! I was hoping to wait for the updated ones to come out but since I'm starting grad school I need to get one now. I'm going to school to study counseling so basically I will be using the laptop for office, Internet browsing, personal use, and possibly some stats programs. I've decided on the MacBook Pro with Retina display but I'm having the hardest time deciding on what size to get. I'm either going to get the base 15" ($1999 one) or the 13" one with 256gb ($1499 one). I am not very tech savvy although I do realize some of the differences between the two. I've always had 15" laptops in the past and I do like the big screen size but the 13" would be awesome to carry around and it would be nice to save some money, although not a deciding factor. I would occasionally like to have two windows up side by side, would this be possible with a 13"? Anyone get one or the other for school and regret it? Which size do most students get? Any opinions would be helpful!!
