Some of the reviews say the sticky stuff gets bad after awhile I have had it about a year so far still working. It is a little bit of a pain because you have to be carful you don't turn it off when you stick it to the mount because the camera is on the back and the touch screen is what sticks to the mount.Your frugal brethren are interested in how you mount your old iPod? Got ine for Christmas a few years ago, it won't be missed if I move it to the plane.
The only problem with most of the setups is you get jello effect with the vibrations inherent in planes + rolling shutter on most of our digital cameras. Especially my SJ's. In bright light the jello drives me NUTS during editing. Ruins the video for long portions of the flight. Throwing a neutral density filter on to the lens seems to help. I haven't had any experience using my cell phone, but now I'm intrigued.
