The display on the pro is gorgeous. If you can afford it and are willing to have the slight extra weight go for it; personally I'd step from an air to a base model 14" pro for the screen alone, but that's my preference, yours may vary. Bonus: you get a better cpu and gpu, better speakers and more ports. The pro feels much more like "zero compromises", whereas the air has slightly downgraded screen and speakers to meet the price point.
But for your needs, either machine will run that in its sleep.
I daily carry a 14" Pro to/from the office (previously had 15" Pro, 13" Pro and 13" Air), it's not like it isn't portable.
