The photo app was designed to be a viewer. Period. The Photoshop express app is worth precisely the price you pay for it. Nada. I use the real Photoshop everyday on my computer and that is where I have space, processing power, as well as a 27" monitor, to work with images. Just use the iPad to show slide shows and email images about and you are using it for its intended purpose.
