Photoshop is $649, Gimp is Free.  Do the math.

Now I really want to have Photoshop but am not inclined to part with the $649 required to get it.  So until my inclinations change I will continute to use GIMP. 

The GNU Image Manipulation Program (GIMP) does everything I need when it comes to image editing.
