I don't have an iPhone, but I have been incredibly impressed with the displays. I did get an iPod touch, which I love. The colors of the displays are outstanding...better than most laptops. It's fantastic as I can load a bunch of jpegs on it and have a walking interactive gallery in my pocket. If I ask someone on the street if I can photograph them, for example, I can take out the iPod and say "here's an example of my work." It works rather well that way. No camera, however. The GX100 is the smallest I have been tempted to use. I have seen some nice iPhone shots...again, it is the color that impresses me more than anything else.
