This weekend I tried to help my grandmother with her new cell phone. She purchased a phone, bluetooth headset, and another bluetooth device that lets you talk in your car handsfree and broadcasts the callers voice over an FM channel that you can tune to with your radio. I got the handsfree device setup and showed her how to use it, but my final recommendation was to take it back to the store. While it was great in theory, in actually use I know it was far more complicated to be useful to me–even though I knew how to work it.
It is easy to get enamored with how something is supposed to make your life simpler to the point that you overlook how it makes things more complicated.
