Adobe wrote in March on a since removed page that it prefers PCs for Photoshop, After Effects and Illustrator, showing that on “equal” machines, the PC outperformed the Mac. Apple responded and stood by their original claim that the Mac is faster.

Then on Monday Adobe announced that they’re dropping Premiere for the Mac. This is major news, but justified since Apple continues to compete against its most loyal software vendors. Final Cut Pro being Mac’s video editing program that competes with Premiere and the new Font Book usurping Suitcase (as problematic as Suitcase has been), being two of the most recent examples. It’s only going to make inter-office file-trading harder, compatibility issues more frustrating. This is not a Mac vs. Windows argument — I simply don’t want to live in a world where there’s an Adobe Photoshop (PSD) format and a Mac photo-editing format, a Quark format and a Mac layout format. OS/2 lost the desktop market because it wasn’t interoperable with the status quo. Thinking too differently is going to make the Mac even more obscure. This isn’t a new argument of course, but this week’s Premiere announcement is disappointing and adds new fodder for the “Apple is dead” pundits.
