Last summer I did a telephone interview with a reporter from the Wall Street Journal, he was asking photographers if iPhone cameras were replacing point and shoot cameras. I had the 3gs at that time so my answer to him was that I was on the fence. Shortly after that I got the iPhone4 and it's camera was a dramatic improvement over the 3gs. It is not good in low light but looking back over my pictures since last summer, 85-90%% are with my iPhone4.
It is just so easy to take the phone out of your pocket and record some HD videos or shoot some pictures. There is another factor that makes it so appealing, the ability to immediately share with the universe the photo you just took. Send it to facebook, flickr, twitter, instagram, posterous (fill in your own social network) and share it with everyone. When I shoot things with my LX3 the first thing I think of is, what a pain it is to post these.
At our wedding this weekend I had a lot of fun taking pics with my iPhone and posting them to Posterous. Posterous is essentially a photo blog I send images too and from there Posterous can auto post to facebook, flickr and Twitter for me.
I have at least 30 apps for processing images and I often enjoy running several apps on the same image. Allison says I am photoshopping on my iPhone. Other times I will just use my standard go to app CrossProcess.
