I am a non-professional but ambitious photographer and I can strongly recommend Pixelmator for almost all users out there. The feature set is more complete than I need, all features are relatively easy to learn because of great training material available and at 59$ it beats everything in the market in value for money. I imagine that professional photographers who depend on specific photoshop plug-ins will miss these at the beginning but they may find work-arounds. Continue with the good work Pixelmator team.
