So ye basically i JUST got my 15 inch i7 mac as the new ones came out. thing is i wud prefer to hav a 13 for the portability. and since now i can hav the same speed and even more ram and space for the same price if i downgrade the screen size.... im really heavily considering selling this one (cant return, took ages to get to russia, but i can sell it here for same price if not more). i rle feel like i wud gain from the less chunky experience, but im almost worried that with the 13" it can start to get cramped there. most of my work is either heavy browsing or Logic Pro and other music related software work. wat u guys think i shud do?
