Not so stupid

Khoi Vinh thinks this new Canon mouse is ridiculous:

As someone who spends a lot of time using Excel, I beg to differ. The mouse is not only a calculator but also works as a numeric keypad for your computer. When spreadsheeting, my right hand is constantly going back and forth between the mouse and the number keypad to enter data. I’m also constantly doing simple arithmetic to check my Excel results. This mouse, if it’s not too uncomfortable, could actually make spreadsheeting more productive and efficient. Although I imagine it might be tricky to get the mouse to stay still when you punch the buttons.
