In the past hour, I have determined that I shall never purchase a mouse with side arrows. Clearly someone thought it was a good idea to make navigating backward and forward between web pages as simple as hitting a button on the side of the mouse right above where your thumb rests. So, what’s bad about that? Navigating backward and forward between web pages is as simple as hitting a button on the side of the mouse right above where you thumb rests. Even when you don’t mean to. And then you have crazy thoughts, like getting out a fingernail file and filing the button down so that it is even with the side of the mouse to prevent further accidental clickage.
