A Hewlett-Packard financial calculator is the only influence that this data-processing giant has had on my life so far, but I know an "HP moment" is dawning ("HP pictures the future," Information Processing, July 7).

As technology increasingly is power, photo filmmakers who do not take technology and customers' convenience as seriously as HP will lose their competitive edge in the photography market. Well done, HP.
