For my new work i'll need to buy a notebook. The weight and the better display will suggest to buy a 13"/128gb/i5 Air for my without-office work. My doubt is that i will have to virtualize Windows for a not intensive MS project usage and need to install Autocad just for drawings check and/or quick changes. It will be used 90/95% with MS Office and e-mail and 5/10% for virtualization ( i was suggest ed to use VMWare fusion). At home i have a iMac that's anough for video, Photoshop music and intensive CAD drawing. Will i ADSL to much to an Air?
