We love the iPhone4.  We just got back from a 10 day vacation in Michigan and it would not have been the same without them!  My Canon Powershot SD800 died about 4 weeks ago after taking 10,000 photos, and my husband left his Powershot next to the charger as we left for the airport at 5:30 am.  I had my Nikon D-80 and lenses but it just not as easy to carry around as our trusty Powershots! We resorted to our iPhone for cameras for photos and videos most of the time and were quiet pleased. The video is great as well! Here are some photos from the trip.
