As far as I can see, the products are basically the same responsive design tool, addressing different frameworks: CoffeeCup framework, Foundation and Bootstrap. The design tool slightly customized in order to address the differences / options in the backend framework.
Pricing: $189, $79 and $49 (for beta) respectively.
This of course raises questions about pricing and product positioning.
Wouldn't it be more logical to have one responsive design tool with multiple - optional - connectors to different frameworks and have pricetags for each? And why not add multiple connectors as plug-ins to the design tool and decide per project which framework to use?
It seems that development focus is moving to new betas while RSD buyers sponsor FF and BB.
Do we really need to buy 3 (or more) products that are - at least form a users point of view - largely similar, if only we wish to target another framework? And now I have to buy BB in order to get RSD V2 for free?
I really love RSD (and FF) but are confused about the direction CoffeeCup is moving to.
It's easy to see, once you see it.
