I use it for photography, and pen pressure is definitely a plus when you feather edges and use masks etc...Working with Photoshop will require both, the tablet and the mouse depending on what you are working on. In my opinion, working with a pen is more reliable than working with a mouse. I find it pretty easy to remove backgrounds using the pen tool and of course the tablet...but one main factors of why i find it easy is because i work with the plugin mask pro 4. In short, using a tablet will make your work easier and faster, of course after you have learned how to use it. When you sit on your computer just think about the time you spend every day retouching, etc... if that's what you do for a living, you might want to consider finding ways on how to shorten the amount of time you spend retouching...as bucket772 previously said, the tablet will give you grater control over details as well, so you might consider that too for professional looking pictures.
