While you're considering the purchase of the latest piece of technology, and pondering whether it's worth every dollar being asked for, you might like to reflect on how far technology prices have fallen in only a few years. Using the magic of the Wayback Machine, you can view the websites of technology vendors from many years ago.
For example, the online shop I usually use, Simline Solutions, has been around for four years. We can see that in May 2000 they were selling a rather hideous Acer 15" LCD monitor for $2000. Nowadays they're $350 - in four years they'be been reduced to 17% of their original price.
