IPOD Remote Control? WHY?

I received an advertisement for an IPOD remote control and I wondered why I would need such a gadget. Admittedly, I love the technology, but WHY?

Isn't an IPOD a handheld device? Isn't it already within my fingertip reach as I am playing it? Why in the world would I need a separate device to control it? I know some people use their IPODs to dock and play the music through speakers and perhaps this is the reason.

Another thing that I always wonder about, is a car radio remote control. I see someone with a small Japanese car, with the windows shaking from the speaker vibrations and using a remote control to adjust the radio or stereo. Why? Can you not reach the controls from anywhere in that car?

I think we are becoming too lazy, myself included. I worked at a company that had doors equipped to accommodate the handicapped. If you simply pushed the big blue handicapped button, the door would automatically open for you and you would not have to use the door handle and use your own ability to open the door. This was very helpful if your hands were full, but time and time again, I would see people use that button and wait for the magic door to open.
