There was and is nothing wrong with the concept of the Adam. In fact, it sold quite well initially, but the issue was one of quality control, which doomed further sales. Coleco as a toy company could get away with dubious quality control for a console, but the tolerances required were much higher for a computer. Once Coleco righted most of the manufacturing issues, it was too late. Obviously, putting the power supply in the printer was foolish and using unrealiable tape for storage were all negatives, but if it worked reliably, it would have been just fine. Losses from the issues with the Adam doomed the ColecoVision, which very well could have weathered the crash based on how it was continuing to sell.
