A lot of people use Macs for design and retouching work so a higher resolution is desirable. I use one for those reasons but on monitors I use two, have for decades. I use one for the actual work and one (of lower quaility) for the pallets associated with the program. Yes, there's key commands to bring them up but sometimes it's nice to have them displayed for like bringing somebody else's art work into the project that may have a different color scheme or say a different paragraph style.
One time (meaning a few years) I was restructuring a ship account. Mother of god what a mess. The original files from the same studio/shop and had different pre-sets to what a point size was based on according to what an individuals computer was set for. Default is usually 72 points/inch but they give you an option to set it to the true measure of 72.272/inch. try coalescing hundreds of catalog pages into one program with the standard setting and that was just for starters. They got away with it because each one did their own sections and not one final print piece. On say illustrator drawings of logos, bring in one logo and the color pallet explodes with all these unused or unwanted colors. Why, because they put 30 different colored logos stacked on each other, grouped on one layer. Then there were the deck diagrams. every single line was a different width, like 1 pt, 1,115 pt, 1,2pt, etc. The type sizes were all different and the individual decks were not in scale with each other so one got imported in at 85%, another at 100 and still none of the work looked like the one next to it. The decks alone took me 8 months to redraw. Don't get me started on the hundreds of maps. Geeks will get what I mean.
