I'm not disputing the value of CC for all of those who never had a perpetual license.
As indicated in the diagram in the first post, that is not the issue. It is the question - when you already own the perpetual license for CS6 - whether the rental payments of $ 1,500 for the first 16 months are worth the extra costs over simply staying at CS6. Are the new 'features and bugs' that much worth to justify the extra cost? What are these 'features and bugs' that generate extra income over CS6 to justify the bottom line result?
You already have the perpetual license for CS6. No costs now or in the future. It has already been paid in full. What justifies the perpetual bondage to monthly payments of around $ 90 in Europe just for some new 'features and bugs' and how does it generate extra income over CS6? That is the question. Not only now, but also in 3 or 5 years time.
