The Internet Oracle has pondered your question deeply. Your question was:
Why do men like power tools so much?
And in response, thus spake the Oracle:
Well, come on down to the workshop, and we'll see what we can come up with.
The first thing on the workbench is a hand-held drill. Turn it on, press it against the wood, and it penetrates deeply, leaving a tight, perfect hole. Look at that! Isn't it a beauty?
Okay, moving on, we have a power hammer. Put the nails in here, thrust it against the wood, and it drives the spike in, all the way, in one powerful stroke. And you can do it over and over again, thrusting the nails in, one after another...
Next we come to the power sander. Hold the edge of the wood against it, like so, and... see that nice, smooth curve? Look at the way it fits into the hand, no sharp edges. Mmmmm!
Power screwdriver. Look how easy it is to put the screws in. And now back out again, with just as little effort. In, out, in, out... I could keep this up all day!
Scroll saw? Look how easy it is to use. It just goes up and down, up and down, violating the pristine, virgin wood and cleaving it right in twain. Oh, yeah! Take it all, baby!
So as you can plainly see, the answer to your question is that a man enjoys power tools because they allow him to create useful and beautiful objects with a professional, well-crafted look.
You owe the Oracle a cigarette.
