Try lugging around an Asus G73 gaming laptop around for weeksThe cMBP is not all that heavy, especially not the 13" model. And its not all that much thicker then the rMBP. I agree with most of the people on this thread about getting a 13" regular MBP. It will be cheaper, have more storage, it will take up the same desk space as the other computers, its just less than 1/4 of an inch thicker (if that).
true true true. Get a regular 13 inch.
