As a Photoshop (from 7 to CS3) to Gimp convert, I somewhat disagree (other people's experience may vary, of course). I actually found Gimp a ton easier to use and more adaptable (and found Photoshop CS3 clunky and bloated in comparison). The biggest issue I've run into is Gimp's lack of layer folders, which can cause issues when getting a complicated PSD from a graphic designer, since all the layers are visible in Gimp.
