There was a time when computers were so expensive that, to own one was beyond the means of a common man and, they were only affordable for the elite of the society. Times have changed and the prices of computers have fallen so drastically that it has been moved from the list of luxury items to the list of essential items in a household. They have become so cheap that you can easily buy a brand new personal computer with basic configuration for just Rs. 13,500/- excluding tax, or a used computer for around one third that price.
