Weight and size are what determine portability for everyone else, not how much water it could hold if it were doubling as a canteen. That's not mass, it's volume, by the way. The MBA is longer, wider, taller and heavier -- yet you've contrived a way to label that as "more portable"... ridiculous on its face. I'm not going to make this valueless discussion thread any longer, so to your reply: those numbers are made up. Larger screens make things less portable, not more.
