I currently use a 15" MBP with a 1 TB hard drive for work and media use. I have almost maxed out my hard drive with media. Therefore, I'm considering getting a 13" MBA to use for work (I need a laptop for work) and either a Mac Mini with TB Display and 3TB external storage or iMac for media streaming and other household computer uses. I've decided to go with the MBA since I travel for work, but a 13" screen is a bit small for every day use. The goal is to have an external display to use as the main screen for the MBA and to use as a secondary display to extend the desktop when necessary. Can the iMac be used for both of these purposes? Otherwise, what are your thoughts on the iMac vs the Mini as a dedicated HTPC with some computing on the side?
