Courtesy the wonderful world of the Intertubes (what else?) comes an excellent item that lends perspective to the pace of technological change over the past two decades.
Steve Cichon, a writer and local historian in Buffalo, NY, happened upon this full-page newspaper ad from Radio Shack circa 1991:
only to realize that the functions of thirteen of the fifteen electronic gizmos listed for sale (including a “microthin” calculator, VHS camcorder, portable CD player, desktop scanner, and a handheld cassette tape recorder) can be performed by his iPhone at a fraction of the cost.
As Cichon notes:
“You’d have spent $3054.82 in 1991 to buy all the stuff in this ad that you can now do with your phone. That amount is roughly equivalent to about [$5224.98] in  dollars.”
The current price for an entry-level 16-GB iPhone 5s? $199
From this perspective, at least, the price of progress looks like a pretty sweet deal.
