I don't like using other devices to check my photos, because they never look very good IMO. They don't seem to have the color depth necessary, and as a result, all the whites are blown, and all the blacks are crushed. My iphone, my netbook, and even lots of cheap TN panels have this issue. I'm not sure what the iPad is like though - haven't seen photos on that yet. If I'm on holidays I'll use my netbook to check sharpness and cull photos, but as for looking at photos to enjoy them, I don't like it.
