my theory: i feel like the first wave of any product is overhyped and has less accountability to deliver.

"Hoverboards (2015) The "self-balancing scooter" became a global sensation almost overnight, with demand skyrocketing across retail and online markets. Because manufacturers rushed to meet this sudden explosion in demand, quality control was ignored. This led to a wave of defective lithium-ion batteries that frequently overheated and caught fire, resulting in massive recalls and bans in several countries.

The Segway (2001) Before its release, the Segway was shrouded in extreme secrecy and hype, with some predicting it would "change the way cities are built." When it finally launched, the reality didn't match the excitement; it was too bulky for sidewalks, too slow for roads, and far more expensive than consumers were willing to pay for its actual utility. "

straight off the top of my head.. Blu-ray . everyone said it was better. it triggered the need to have "the latest greatest tech" but now.. i dont even know how that would have benefited me, personally. it would have been more rational if they had a more tangible benefit.. like a smaller disk.

also gameboy. ..however i cant think of any criticism aside from costing alot.
