First and foremost, look at the article's title "Death By GPS in Desert," thus leading the reader to immediately assume the GPS was the cause of death--not stupidity. Next, some of the sub-titles add to the headline "Not All GPS Units Reliable," a statement that is not really as accurate as the GPS units themselves. Most GPS units are extremely reliable, but like computers, they only do what you tell them to do.
GPS units are no more complex than a cellular telephone that has all the bells and whistles. The problem is that most people don't take the time to read the instruction manuals that come with them. Of course, some people cannot read at all, or they're just too damned lazy to read the manual, then wonder why something doesn't work the way they want it to work. Hmmmmm! Kinda like trying to use a sextant without first reading the book and learning how to use it. Imagine that!
