I've been using it since version 3.0. I am a computer guy and I never hang on to old versions of anything when a newer version comes out. I never noticed much of a change in the tools or workings of Photoshop at all from one version to another, only the addition of more functionality. It's hard for me to imagine that anyone would hang on to version 4 when they could have features like the History Palette and brush, extremely valuable for photo restorations and touch-ups. Gromit
