I was curious, that's all. I'm not a image-manipulation person (the largest amount of image-manipulation I've done involved porting an algorithm to do some stuff from C++ to python), only have cursory experience with both Photoshop and the GIMP, but have heard both "It's no replacement!" and "It's a perfectly good replacement" from people I know who do have a lot of experience with image-manipulation.

I know, for instance, that the interface is wildly different than photoshop's, and was curious as to how much time you had invested into examining it.
