Nearly 15 years ago, Apple released the Twentieth Anniversary Macintosh, known ever since as the TAM. It was the first major project at Apple of a promising young designer named Jonathan Ive, but despite offering many of the design ideas and technologies that would define Macs for years to come, it didn't do well as only sold around 11,600 units. A rare "new in box" TAM has now appeared on Ebay, the machine and accessories having never been used.
