The creative use of the iPhone is, I find, stunning. Every day I receive press releases for apps that I just wouldn't expect. Two new apps that illustrate this are Retina and Eye Glasses. Retina ($.99) is for those who are color blind. You simply point the camera at something, such as an item of clothing in a store, and the app will show the item in the camera's preview mode and tell what color it is. Eye Glasses ($2.99) lets you use your iPhone to see tiny text or other hard-to-see details.
