So why is having a mechanical shutter so great for the DX?

That's one feature that many reviewers point out without really adding any information as to why.

So if other phone cameras do not have a mechanical shutter what do that have.

Do we know the number of actuations the shutter is rated for

i hadnt noticed this in the reviews of the X but to answer your question...most phone cameras have electronic shutters. basically there is a lot of additional electronics required at each pixel in the sensor to store the charge (light) that has accumulated while the electronic shutter is "open." all of this additional circuitry takes up space that could otherwise be used to enhance the quality of the sensor. so with a mechanical shutter, moto could use a higher grade sensor that is capable of gathering more light with less noise, etc.
 
That's what's been implied in the reviews I've read. The picture quality appears to be the best around for the moment.

I'm less concerned about number of pixels as much as capturing sharp accurate images and performing better in low light situations.
 
The mechanical shutter eliminates the shearing effect often seen in cell phone pics when something is moving horizontally. This is because the electronic shutter in most CMOS sensors only works on one line at a time as it scans the sensor vertically. So the lines at the top of the image are exposed at a different time than the bottom lines, resulting in a "tilt" to things like a passing vehicle. It might also be that the electronic shutter in this sensor doesn't work very well (doesn't fully reset the pixels to 0 at the start of exposure), and it needs a little help.
 
Ahh thanks, I was wondering how the electronic shutter works and now I see the side affects from using one as well.

Exactly, quantity vs. quality. MP is nice but sometimes its the quality that it needs
 
i saw some pictures some guy posted and notice that the f-stop was 2.8f and it had a nice Depth of Field-
I use a Canon for taking pictures and the DX amazes me for a point n shoot-
