I became aware of how useful a GPS can be when I was on a plane trip with a literary rock band I belong to called the Rock Bottom Remainders, which has been hailed by critics as having one of the world's highest ratios of noise to talent. On this trip were two band members whom I will identify only as ``Roger'' and ``Steve,'' so that you will not know that they are actually Roger McGuinn, legendary co-founder of the Byrds; and Stephen King, legendary legend.

We were flying from Chicago to Boston, and while everybody else was reading or sleeping, ``Roger'' and ``Steve,'' who are both fully grown men, were staring at their GPS devices and periodically informing each other how far we were from the Boston airport. ``Roger'' would say, ``I'm showing 238 miles,'' and ``Steve'' would say, ``I'm showing 241 miles. Then ``Roger'' would say, ``Now I'm showing 236 miles,'' and ``Steve'' would come back with another figure, and so on. My wife, who was confident that the airplane pilot did not need help locating Boston, thought this was the silliest thing she had ever seen. Whereas I thought: I NEED one of those.

So I got a GPS for Christmas, and I spent the entire day sitting on a couch, putting it to good use. Like, I figured out exactly where our house is. My wife told me this was exciting news. I think she was being sarcastic, but I couldn't be sure, because I had to keep watching the GPS screen, in case our house moved. I also used my GPS to figure out exactly how far my couch is from LaGuardia airport (1,103 miles). There is NO END to the usefulness of this device! If you're a guy, you need to get one NOW, so you can locate yourself on the planet. While we still have one.
