not sure which section to post since it involves 4 different apple products but I will post here since it has more traffic. I am planning a major upgrade of my computer ecosystem. Right now I am just using a 13 inch notebook on loan, but plan to get another notebook for travel and a large screen for at home use (definitely preferred when watching videos, playing some games, etc) but not sure what the best way is to approach it. option 1. 11 inch Macbook Air (the cheapest and most mobile apple) and a 21 inch iMac? option 2 13 inch MBP and a thunderbold apple cinema display? these should cost nearly the same neighborhood also open to other options.
