It's all about easy to use. Easy to use saves time (and money).

Gimp can do what Photoshop can do but it will take you twice the amount of time. If time is not an issue it's not a problem.

Some things slowing you down in Gimp:

  Working with text.
  A layer has a size.
  Out of focus problems of your tools and working area.

Text and out of focus problems are solved in the upcoming Gimp 2.7.
