What is the importance of miniaturization?

The discussion at the web page (below) is: About Miniaturization in Computer Technology

The semiconductor industry is competitive and endlessly endeavors to replace yesterday's computer technology with smaller chips, with features as small as a thousandth of the width of a human hair. The idea is to get more transistors on a single chip. Increasing the number of transistors ultimately leads to more power in the computer, cell phone, handheld PDA and other electronic devices that have a computer chip inside. In our times just about every electronic device has a computer chip inside. The pursuit to make these devices more powerful, and thus effectively independent of a constant power source, is the focus for miniaturization in computer technology. Ultimately the goal is to have computers everywhere by making components smaller and more powerful. These days you can buy one megabyte of memory for less than a stick of gum
