It's surprisingly difficult to find a good, free image editor for Windows; how refreshing then to come accross the wonderful Paint.NET. With layers, history (undo), photo editing tools & export to most common formats it will do a good enough job for most people. While the website sure reminds me something the app has one of the most stylish and friendly GUIs ever seen on a freeware app. Microsoft could do worse than make this available as an official update to Paint.
