I'm in the market to get a new ultrabook (looking at the Air, a maxed out one with i7 and 8gb ram). I do some occasional video editing using Premiere Pro CS5 and After Effects (rarely), as well as some audio recording, and graphic design using the whole Adobe Creative Suite. I'm wondering how these apps run on the Intel HD 4000 integrated graphics chip? Is everything compatible compared to if I had a discrete graphics card?
