Let me be completely honest with you. I have a full-blown mouse fetish. I've owned every single major mouse model from Microsoft and Logitech since the bad old days of the original Microsoft "Dove bar" mouse, and the Logitech MouseMan. I remember quite clearly bringing home my first mouse, an add-on for my Apple //c, and demonstrating this novel method of input to friends. I've been obsessing over these essential input devices since way before the days when USB was just a glint in Intel's collective eye; I have more than my share of mousing experience.
