I have both the 13"Macbook Pro and the 13" Macbook Air and here's what i can share based on my experience
MBP
Pros:
- I have 8GB ram and a 1TB HDD on my MBP, i can store alot of raw files and photos/videos on it. So you can edit and keep everything on the notebook as well as an external HDD for additional redundency
Cons:
- It really is very and i mean very heavy..last i weighed it it was 2.3kg. Very hard to bring around when travelling
MPA
Pros:
- Very thin and light at only 1.3kg
- It's actually faster than the MBP because of the SSD drive. The processor may be slower than the MBP and the RAM only 4GB but the SSD pretty much makes up for it.
- Perfect when travelling. Although only 128GB (after softwares, maybe only 100GB left), it's ok for a few days of photos and editing while on travels.
Cons:
- Only 128GB SSD so you can't keep much stuff on it. You will need to save to an external HDD after you return from travels or editing..
- Only 4GB or RAM so i don't think it works well for video editing. Besides video raw files are very huge and the 128GB SSD wont be enough anyways. I don't do video though
Summary: I use my MBA for all my travelling and if i have to bring a notebook out, it will be the Air..The pro is a workhorse but only at home
