We have bit of insider joke at work about state of compulsion. It is unmistakably diagnosed when someone is deep into googling or talking (to no one in particular) about purchasing or upgrading some tech toy.
If you get bunch of techies together they will most probably iron out common preference about everything. It may become a vector hard to go against.
When locked in such environment for a long time sense of perspective is lost. I had colleague that argued about inferiority of AMD processors by saying that friend of his relative had one AMD CPU overheating (several years ago). Made no sense whatsoever, but for him buying (or keeping if he got one) AMD processor became shameful choice – something not approved by others.
Crowd preference is bad enough for brands, but outright ugly for generations of technology. How many people you know that use mobile phone several years old? How many of those who change it every year actually need new one every year?
Another strong factor is that tech devices are often turn out something different from what they were bought for. As in classic case of computer purely for work. That is soon brought up to highest gaming standards, at a cost that may exceed its original price.
When our expectation fail test of time it puts us in vulnerable state, feeling of mistake that must be fixed… Most probably by buying newer device that will fail expectations just as well.
Progress of computers and gadgets has little to do with real needs and curve of computing requirements. Most of the time it is simply our shame of staying behind.
Had you ever bought something just to replace perfectly working item, shamed into no longer liking it? :)
