Hello, I currently have a 15 inch laptop (not mac) and just bought a 13 inch Air (8G, 256 G, 2.0 ghz). While I have seen the screen size in the store, I have a hard time figuring if the loss of real estate in term of screen size if really a bother. I mostly do web, emails, work and excel. Have some people with the same usage pattern as I have made the same switch? Thanks. PS: I looked at the 15 inch retina display but would rather go with the Air if smaller screen size is not a big issue due to the form factor of the Air.
