Sorry to say... the Cube's design might have been awesome but the execution of the final product was flawed... cracks in the plastic were very common... and the on/off button didn't always work. It was Apple's Edsel.
Actually, I think a quite a few people would agree that postponing more rollouts would help alleviate some of the backorders from the initial week. I don't think anyone said to wait 6 months. Hell... if it took Apple 6 months to supply people from the initial rollout then Apple has a really big problem.
