I was referring specifically to those saying that the iPhone can replace all these devices
Phones like the Motorola Zine ZN5 , and sony k850i have amazing optics and are slowly getting close... but the iPhone is worthless for pictures
Oh hey look i can take a picture of a beer, that is one foot away from me... standing still, in a well lit area
even still your picture is grainy and not that well focused.
A camera's goal is to capture a moment. Sure sometimes its a picture of some delicious beer, other times though its a picture of your friend tackling your other friend ( see below).
It's not the best camera. Nobody is claiming that. It's near rubbish. Still, I don't hardly cary a digicam around because it works and is really easy. I do have one though, so it's not phased it out totally yet. I have a point and shoot (not a cheap one, it's a cannon powershot) and I use it when I'm going sight seeing, but I don't have to cary it around all the time because of my phone's camera.
Also, I don't know of a bar that's well-lit. It was fairly dark, the phone compensated by changing the aperture. This also makes things blurry if you're not careful. It is conceivable that these phone cams will get better and phase point and shoots totally out.
