Oh well, why do you need a camera in a smartphone afterall? Yesterday, the camera of the Samsung BlackJack from Cingular came to the rescue at our favorite sushi place, and helped us capture the handwritten "specials" menu which was hanging on the wall next to the sushi bar, as we walked to our table. The wait staff went over the menu anyway, but the captured photo and the BlackJack zooming capabilities were the real savior. We were able to take our time to review the menu and make sure we didn't miss any new and unique items.
So if you're in the process of selecting a smartphone, and you're wondering on whether you need this camera or not, it is almost certain that you will have many good uses for it. Not necessarily capturing menus at restuarants, but maybe caputring company and product information at tradeshows and conferences, or whatever else is important to your business.
However, you want to keep in mind that some companies do not allow you to take your smartphone with you inside their premises if it has a built-in camera for security reasons--something to keep in mind as you make your smartphone selection.
