Personally I think Adobe is starting a new trend here. These products are "Productivity" products that are completely designed with the tablet in mind. My criticism of the tablet space was the lack of "productivity" apps for tablets. If more and more developers start delivering these kinds of products the tablet market have an explosive growth even more than today.
