Ordered rMBP 13" straight after the presentation and now wondering whether to return it. For me mobility is very important. The main things I do are Office/Browsing/Movies with occasional connections to external displays. Money difference between three is not an issue to me. Thus, I am wondering whether quad-core and nvidia worth going for 15" and, thus, had a bulkier piece of equipment. MBA I believe is out of the equation since it is a bit outdated. I cannot wait for Haswell, because I have a month left to get my HE discount. What do you think?
