I admit that many folks out there really prefer Photoshop over every other graphics app. Eve though the Gimp is as featured packed and as easy to use, folks just prefer Photoshop. I understand. But the challenge was always that Photoshop was not being written for Linux. The folks at Adobe made Photoshop for Windows and Mac, but not Linux. Enter Disney.
At around the same time as my trip to Walt Disney World (give or take a few years), the Disney animation studio was adopting Linux. The animators wanted Photoshop running on Linux. Since Adobe wasn't providing this, Disney decided to fund a project to port the Windows version of Photosop to run on Linux under Wine. And that's why, thanks to Disney, Photoshop runs on Linux.
