A mouse is a terrific thing to use in the right context. Selecting an item among thousands or clicking an arbitrary position (for drawing something or selecting items in a graphical context) is an order of magnitude faster with a mouse.

Navigating a complex webpage with the keyboard is painful even if tab order is perfect.

Starting a command that you have a keyboard shortcut for is perhaps slower with a mouse - so use the keyboard then. But I suspect I do more of the first kind than of the second. And yes I'm a programmer.
