When the new Notebooks and iMacs come out, I'm going to need to decide what setup I want to get. I'm trying to decide between the following options: 1) New iMac w/ 2TB Hard Drive and backup 2TB Thunderbolt Hard Drive 2) New Macbook Air w/ Apple Thunderbolt display, 2TB Thunderbolt HD, and backup 2TB Thunderbolt HD I estimate that The Air setup would cost about $300-400 more. I would gain flexibility of taking my air to other locations, travelig, etc. I would lose processor speed. How much? I would gain OS HD speed. (the OS would be on the internal flash drive, right?) Looking for thoughts and opinions.
