I usd to agree
Until work gave me a Blackberry that has a phone. I'm surprised how often I use it.
See something interesting in a shop, but I want to do some more research online when I get home, so I take a photo of the label.
Need to get the serial number off the back of the machine, but can't get my head into that small space - stick the phone in there and take a photo of the label.
See an interesting personalized license plate in the parking lot - take a snap, just because I can, and I have a camera right there.
See an amusing sign on the street - take a snap, just because I can, and I have a camera right there.
See a poster for an upcoming event that I might want to go to - - take a snap, so that I can look up the details when I get home, and I have a camera right there.
Need to make a note of any error codes or messages that come up where a screen print won't work (a Blue Screen, when you're in the BIOS, on the login screen, etc).
If you ever need to talk someone at a remote site through the process of doing a hard reset of a box in a remote server room, it's very handy if you took a snap of that rack the last time you were there, and can add labels and e-mail it to them before they press the wrong button.
Need to root around on the bosses desk while he's at lunch - take a photo of it first so that I can put everything back the way it was :-)
And then there's the requisite photo's of various small children, animals, colourful sunsets etc, a couple of videos taken at the fireworks, the sort of snapshots you take with a cheap and cheerful digital camera. So I never would have picked a phone because it had a camera, and I'd never use my phone when I wanted to take a "photograph" rather than a "snapshot", but it's turned out to be a surprisingly useful tool to have available.
