Image of the Day: graph showing price of memory from 1955-2010

This graph illustrating the price of memory and storage over the last 55 years, done by John C. McCallum over at MIT, has a pretty distinct trend. It makes me want to travel back in time with a handful of flash drives so I could make enough money to retire.
