I used PSP in the mid-90s and gave up on it when I got sick of the annual update-for-the-sake-of-it offers. Being in a transition between Windows and Linux (Ubuntu) for the past three years, I've adopted Gimp as my preferred graphics edit tool. The Linux version runs nicer, but the Windows vsn is reliable. The UI is a little quirky, but you get used to it and I don't find it hard to get things done. I use it mainly for my hobby of creating Google SketchUp models for the Google Earth 3D Buildings Layer, to produce photo textures for the models.
