I'm considering packing away my old Macpro with it's esata RAID. I want to slim down. I was able to edit my last project in the clients office on the 1st gen Mac Air with only a few hiccups. Is the new Mac Air 13 i5 capable of editing HD video? I would like to be able to just use the Macair- a 27 TB display and a TB drive. My projects are fairly simple. Events, webiste promos, Interviews and photo montages.
