It has been a long time since I got excited about a mouse...[Ed. Digression: The first time I was travelling to camp with my mother. I was 8 years old and we had just checked into the Mackinac Island Grand Hotel. My mom was taking a shower while I watched TV. Suddenly, there was a shreek...and she ran out of the bathroom clutching a towel so as not to scar me for life, screaming wildly, pursued by a little grey mouse that disappeared under the door to the room. It is hard for a battery driven mouse, however nobly designed to compete w/that memory for excitement.] This Logitech Anywhere Mouse MX does the trick.
