Mice are anathema to people who are comfortable working at a keyboard, and Hewlett-Packard Co has taken a licence from the inventor, Craig Culver of Woodside, California for what could prove a much more acceptable alternative: it is called the Isopoint and according to the Wall Street Journal is a cylinder about the diameter of a drinking straw that appears to run along between the space bar and the leading edge of the keyboard; it is manipulated by the thumbs and can be slid to the right or the left to move the cursor in the same direction, rolled to move it up or down, and is depressed to execute a command; we could live with one of those.
