Has anyone used one of these? A friend of mine, who has sold a number of photos taken with her iPhone swears by it. The lens simply clips onto the phone and adds wide angle and/or macro capabilities. I'm not sure I'd go out and buy one (and those of you who look down your noses at phone cameras -- I have two Nikon DSLRs I use regularly), but I've made it a gift suggestion.
But not wanting to wait to see if my daughter follows through on my suggestion, I thought I'd query the assembled shutterbugs here.
