I realize this has been the subject of innumerable discussions, but ...
Although I do not prefer the approach, my opposition to using the cloud concept for use of Adobe's applications is not as vehement as most of the photographers and other Adobe product users I know. However, if I understand the Adobe pricing structure for Creative Cloud usage I'm upset with the change.
I am currently looking at my long-running list of applications with their serial/registration numbers. The list includes Photoshop, Photoshop 3 and 4, Photoshop 7 for PC, Photoshop CS2, Adobe Creative Suite, CS Master Suite, Creative Suite Premium 2, CS3 Master Collection, CS4 Master Collection, CS6 Master Collection, and many, many more Adobe applications like various versions of Illustrator, InDesign, Photoshop Elements, Dimensions, Acrobat, After Affects, GoLive, LiveMotion, Pagemaker, PageMill, Premier, Streamline, Type Twister, and more. These purchases make through the years were always significant and ofter quite difficult on my income. If there should be doubt about the authenticity of the above list, as indicated at the beginning of the list, serial numbers are available for each and every one of the applications, suites, and collections.
To me this is very significant ownership and support of Adobe products with an attendant very high cost. Yet, if I understand the Adobe Creative Cloud pricing structure, someone that has purchased a single Adobe Creative Suite, CS3 or later, or even one product from one of these suites, can obtain use of the Creative Cloud, whether for one application or the entire Adobe CC suite, for exactly the same price I have to pay for the CC usage. I think this is extremely unfair.
