   It's undeniable： Being among the first to try out a new piece of technology is cool． There's the excitement of doing what has never been done before the feeling that you're living in the future． And when you're the sole member of your social circle with the latest hot gadget， people stare in fascination． They ask you questions． They see you as the holder of powerful， secret knowledge for a little while， until the next big thing comes along． People tend to underestimate the costs of this temporary coolness， which they pay in more ways than one． Don't fall into the early adopter trap． Don't join the first wave of consumers who invest in the latest media﹣hyped hardware： instead， wait and see．

   To put it frankly， early adoption is a bad investment． First， the earliest versions of devices are not only expensive， they are also the most expensive that those devices will ever be． Companies are presumably attempting to recover the cost of production as fast as they can， and they know that there are serious tech﹣lovers who will pay a great deal to be first． Once the revenues from early adopters' purchases are safely in their hands， they can cut the price and shift to the next marketing phase： selling the product to everyone else． This is why the cost of the original iPhone dropped about U． S． 200 only eight months after its release． Plus， electronics hardly ever become more expensive because intense competition in the industry puts downward pressure on prices over time． Prices of gadgets will fall shortly after release， and they will likely keep falling． Many new TV models drop significantly in price as little as ten days after hitting the market． Further， electronics rapidly depreciate because they become obsolete （废弃的） so quickly． This means that early adopters pay the maximum price for an item that does not hold onto its value． The resale price of a cell phone or laptop can drop by fifty percent within just a few months．

Speaking of becoming obsolete， those who are first to leap into a new technology risk wasting money and time on something that will never catch on． Another good reason to resist the early﹣adoption temptation is that the first version of a product typically has defects that cost a lot in time and frustration． Such problems are so common with new technology that early adopters are basically unpaid beta testers and troubleshooters． Unless this sounds to you like a fun way to spend your time， don't be among the first users． If you wait to learn what the problems are with a new electronic gadget， you can look forward to a smoother experience or choose a less troublesome product．
