If it weren't for Apple, Adobe wouldn't EXIST. Considering what Photoshop was first developed for and solely for Macs for several years. And the only reason Adobe even still bothers to develop for Mac is because of the very high percentage of the design community who are married to their Macs and won't use anything else. If I recall correctly, something like 40% of Photoshop installs are on Macs, which considering the general desktop userbases percentages is fairly dramatic.
