25 years ago, IBM introduced the personal computer.  At the time, the idea that people would use computers in their homes as part of their everyday lives seemed far-fetched.  I've worked as a computer programmer nearly as long as PCs have been around.  I've seen tons of changes in that time...  from black screen with green print to dazzling colors and images... from DOS to Windows... from the Internet being a tool for scientists to the World Wide Web as a school, playground and marketplace for the world.
