I can't compare with the Samsung, but I have a Nokia slide with a 2MP camera. It takes pretty decent pics, comparable to the Samsung. Good outdoors, sucks indoors because it only has a LED light for flash.
I have a good digital camera, but I found that often I wished I had it with me and didn't. So I figured that with a camera phone, even if it did not take the best pictures, at least I would have some.
