I'm currently debating between a 15" MBA with 16GB memory ($1461), a 15" MBA with 16GB memory and 512 GB storage ($1673; $212 over the 16GB only MBA) and the MackBook Pro 16" ($2437--$763 above the MBA with 16GB; $551 over the MBA with 16GB and 512GB.). I often split the screen with documents, so nothing I do is too intensive, but larger sizers are nice to work on. I can make the price of either option work, but I don't want to spend extra money if I don't need to. What do you think?
