I'm looking at buying a macbook for school etc, and I'm debating whether I will buy the Air 13" with 8gb ram and 256gb storage, or the Pro 13" with 128gb storage and 4gb memory, but with a better processor. I'm primarily going to be using it for taking notes, a little bit of non-intensive photoshop and video editing and garageband. I just think that the 128gbs will be a bit small, and as the 4gbs ram is soldered on it would be a pain to upgrade in future. Thoughts? Thanks
