Craig Newmark points to a great website "Classic PCs vs. New PCs: Their True Cost: Doing the math makes technology's relentless progress even more amazing," where they compare the costs and specifications of various computers from the 1970s and early 1980s to today's computers.
One example is illustrated above: a 1984 Apple Macintosh vs. a 2009 Apple iMac. Adjusted for inflation, today's Apple iMac is 26% cheaper ($3,849) than the 1984 Macintosh ($5,186). Measured in the number of hours of work at the average hourly wage ($8.48 in 1984 and $18.57 in 2009) to purchase a computer at the retail price in current dollars, the price of an Apple computer has fallen by almost 30% (294 hours in 1984 vs. 207 hours in 2009). But what's maybe even more interesting is to adjust for the phenomenal increase in computer power, and compare the real dollar cost per CPU (MHz) and RAM (KB) in 1984 versus today. Here's that comparison:
Real Dollar Cost per CPU (MHz)
1984 Apple Macintosh: $662.35
2009 Apple iMac: $0.34
Real Dollar Cost per RAM (KB)
1984 Apple Macintosh: $40.52
2009 Apple iMac: $0.00025
In terms of the cost of processing speed (real dollars per MHz), the 2009 Apple iMac is 1,947 times cheaper, and in terms of memory cost (real dollars per KB), the 2009 Apple iMac is 162,000 times cheaper. And keep in mind that the 1984 Macintosh didn't even have a hard drive - you had to store all of your files on a floppy disk!
From the website:
"Computers today are mind-blowingly more powerful than they used to be. More importantly, consumers get vastly more computing power and capacity for their dollar today than they ever have before. The low end of the market gets lower, and the high end…also gets lower. It’s very difficult to buy a non-diamond encrusted $10,000 PC, much less a $20,000 one, which you could do back in 1980s without breaking a sweat. But it’s easy to buy a steel-encrusted $350 bargain PC that’s just as powerful as a top of the line model a few years ago.
From this simple analysis of computer cost, I suspect that baseline desktop PC prices will continue to decrease over time. To what end and how much, I’ll leave to professional market analysts. But I do know that, in the computer industry at least, the past is often a good indicator of broad trends that will continue to unfold for years to come. I eagerly await the days ahead."
MP: If the dramatic price reductions and quality/speed improvements of computers and other electronic products happened suddenly all at once, it would probably be declared to be a miracle. If nothing else, it would certainly catch our attention. But when the price reductions and quality improvements happen continually and relentlessly all the time, we become immune and either don't even pay attention, or tend to take the improvements for granted.
Thankfully, the comparison of today's economy to the Great Depression have started to fade, because it was easy for many to think our standard of living would somehow return to the level of the 1930s. This comparison of computer prices helps us appreciate how technological improvements elevate the standard of living of the average American to levels that previous generations couldn't have even imagined. Another lesson here might be that even a Great Recession can't stop the progress of human ingenuity, technological improvements, and the entrepreneurial spirit that will continue the relentless trend towards better and cheaper products, and a continually rising standard of living.
