So I downloaded GIMP 2.6 and began to play around with it. I created a very simple image to begin. Being a simple image it took me about 30sec-1min to create. As an experiment I attempted to replicate the image in Photoshop, Paint and Photobie and all three programs required a lot for time to create a similar image. However as I began to develop more complicated images I found GIMP to be someone cumbersome. Here is a short list of pros and cons.

Pros
Brush selection toolbar - Much simpler to use than Photoshop's scroll menu. Also the edit brush option is very easy to use. There are also some cool default brushes like the clover.

Layer option - There are a lot of layer options in the toolbar including an easy way to create a layer mask

Extra tools - Tools like the rotate tool, shear tool etc make it easier to manipulate whole layers.

Cons
Brush Options: Although the option to create your own brushes is there a lot of the defaults I use in Photoshop are missing. Most of the basics are there at least.

Text Input - A major pain in the butt, when trying to move your text, resize the box etc. The default text box is very finicky and if you select the wrong spot you often go back to the actual text edit. Did I mention that the text edit is in another mini-window that pops up? It can be very frustrating when you are simply trying to resize the box.

Lack of tabbed images - I find it more efficient when cutting out parts of an image and moving them to use tabbed images like in Photoshop. GIMP unfortunately doesn't offer that.

Overall I found GIMP 2.6 to be a fairly decent program for minor image creation. I haven't delved to much into photo editing yet so we shall see the final results.
