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.

The MBA is less than an inch longer and wider (because of the larger screen). It’s not as thick (‘tall’?) as the Surface Pro and it weighs less (2.38lbs) than a Surface Pro with TypeCover (2.55lbs).
