Ok, so you're saying that you wouldn't have any problem manipulating some complicated photos (changing backgrounds, masking out certain elements, changing color levels, creating alpha mask, adding drop shadows to text, touching up a person's face, blending several layers together so that the layer below comes through to the layer above, etc, etc) in Microsoft Paint instead of using Photoshop?
After all, they're both just "text editors" as per your example.
