I use InDesign, Illustrator and Photoshop for my job where I have a 21" iMac and smaller external screen. 75% of my work over the year is WordPress, remainder is InDesign, Illustrator and Photoshop in that order (no real video work or heavy use of filters/rendering but I don't especially want much lag either). I want to be able to work at home, especially over the next few weeks until mid-April this year when a big InDesign + Illustrator project needs to finish. I don't want to buy a new laptop next week if the retina MBA is coming in June, but I need something for the next 8 weeks. So - will it work for me to get the mid-market Mini 8gb ram and a new 23" monitor, so if/when the retina MBA arrives I can use it with the external monitor?
