I know that it is a sensitive topic but a lot of other companies are switching to the subscription model. When Photoshop and Illustrator came out with a subscription, I was hesitant, especially at 50 dollars a month. However, looking back, I actually love the subscription model.
It's easier to update and there is always something new feature that comes along that makes it worth it.
For 99 dollars a year that about 8 dollars a month or 27 cents a day. I know that can be a lot of money in some areas but if you live in the developed world it really isn't that much money. Chances are you spend more on pizza than software. At 8 dollars a month it's cheaper than a photoshop license (19/mo).
After working with the alpha, C3 is totally worth every penny. I look forward to the full version. It will be the easiest way to get your idea out there for the least amount of effort.
