Ignoring all other factors... For a college student, would you consider the MBP 15 inch to be portable enough? I'm afraid the footprint might be too large for the average college desk, etc. Weight doesn't seem to be too big a factor (only 1 pound heavier). Trying to decide between 13 inch w/ 16 GB RAM or base model 15 inch. Will buy whatever the latest edition is after WWDC.
