In 1991 the very first and spectacular example of computers becoming smaller and the hardware and capacity becoming much better is the HP 95LX palmtop PC. A computer that was the size of a small calculator but had the same computing power as a desktop PC of the time. Think about how much has changed in the 10 years since HP introduced their first desktop PC  That means that in a period of 9 years they changed from having computers that took up whole rooms to ones that fit inside your pocket and had easily as much computing power as the earlier desktop PC's this is just amazing to ponder upon.
