Cons
Con Moderate learning curve
Con Expensive [$289-$589]
There is a free trial to work with Axure, but there is a hefty price for the standard edition at $289. Even more so, the Pro edition will cost $589.
Con New features are not tested thoroughly
Since releases are so often and with little time between them, usually new features are not tested a lot and this can bring a lot of bugs with them. Which fortunately are quickly patched in the next release.
Con Documentation is lacking
Krita's official documentation is incomplete in some areas, especially for new features that are constantly added. But this is compensated with it's great design and usability which makes it easier to understand how things work.
Con Poor touch controls
They are still pretty much a WIP. But they are getting there.
