Most of you don't seem to realize how negative this is.
Apple is making some big enemies lately, and they might end up regretting it. If the entire Creative Suite was discontinued for the Mac, do you think Mac-based CS users would switch to an alternative program suite, or switch to an alternative platform?
As a graphic designer/photographer, I can tell you in no uncertain terms that there is no workable alternative to the current indesign/photoshop/illustrator/flash/dreamweaver/acrobat workflow.
What Apple has done is akin to Adobe restricting PDF viewing permissions to Adobe Reader/Acrobat programs only, and blocking future PDF document versions from opening in "Preview" or any other non-Adobe app.
Apple seems to think that the momentum is on their side, but they don't realize how fickle people can be. Google could easily disable maps on all apple products, disable youtube on iphone, disable gmail access from apple products, and whatever else they have that people rely on, and believe me, if that happened, I would leave Apple before I left Google. I will not ever change my email address again if I can help it. There is no viable alternative to the Adobe Creative Suite. If Apple wants to ruin that relationship, and users are left to pick between their career or their computer OS, I think that's a game Apple will lose. Do you realize how many Macs are sold into college and high school campuses every year because of the Creative Suite alone?
