With something like QuickRes I can quickly change the display resolution via a key command to (for instance) see all the channels in a large mixdown I'm doing for someone. Sure it can be pretty tiny, but for a birds eye view of things and being able to quick adjust track volumes in large projects, it's a huge time saver not having to scroll all the time.
hmm there seems to be a room for recosideration about which environment is more effective, to work in a retina display with its resolution swithced to tiny texts frequently or in a secondary display dedicated to a mixing.
While not many apps are shipping in retina resolutions,....
In the unsupported software the resulution is nearly overly high. I think this resolution doesn't serve enough as an incentive to make people tolorate bluring text/graphic here and there in less dpi and think it's worth to buy. But I agree that mainstream laptop resolution will get higher in the future. And after that the market and softwares would be ready to adopt more pixels for their GUI.
