It wasn't long ago that digital cameras were a true oddity. That's not the case anymore.
Digital cameras are mainstream, and selling in record numbers.
This sales explosion didn't happen in a vacuum. After all, there wouldn't be nearly as much interest if digital cameras only did what your current camera does. Rather the market leaders today, Sony and Kodak, provide products that open whole new possibilities. One of the big reasons that digital cameras have caught on is the Internet. It's one thing to send email, it's quite another to send mail and pictures.
