This site on the history of storage pricing is interesting. According to them, the company XCOMP was making hard drives for about $190 per megabyte in 1983. By that pricing, without adjustment for inflation (which there has been an awful lot of since 1983), the new 1 terabyte firewire drive I just bought would go for 190 million dollars today instead of the 500 it sells at.
There are some great photos on the Computer History Museum website, like this one of the first portable computer. Check out that spacious display.
