Fatal flaw(s): Expensive, underpowered 

Steve Jobs loves cubed-shaped computers. When he started NeXT Computer Systems after being ousted from Apple, its main machine was the NeXTcube—a high-end workstation shaped, like, well, a cube. Fast-forward seven years later, Steve was back at Apple, and he was again trying to pitch the world on a high-end cube-shaped workstation. This time around, the Jonathan Ives-designed piece was absolutely gorgeous. An 8"x8"x8" cube suspended in acrylic; from afar it seemed to be floating. However, it's hefty $1,600 price tag brought consumers back to the ground mighty quickly. After only a year on the market, Apple pulled the plug.
