I don't really follow the argument you are making here. Sure, you can take nice photos with a mobile phone if you have enough light and are not worried about the noise and the stripes and are happy to view them at half size.
But someone with the skill to compose a nice photo will achieve more by not using the crappy excuse for a camera built into their phone. This is especially true since the phone manufacturers insist on increasing the pixel count, when a simple low noise 1.3MP sensor would make a hell of a lot more sense.
A previous Nokia mobile with 1.3MP used to take nice grain free photos in a variety of lighting conditions. My current 2MP sensor produces stripy grainy images almost all the time.
Besides, a large part of producing decent photos is knowing when to override the default exposure settings – good luck doing that on your average mobile.
