Apple has deleted the 667MHz Power Mac G4 from its hardware range, four months after its introduction.

The 667MHz model is missing from both the US and the UK Apple Store's product lines.

Apple had planned to phase the model out, according to
MacCentral, but the company has not explained why. MacCentral speculates that the 667 model does not fulfil any market niche.

Industry observers believe US resellers have found it hard to get hold of the configuration. The 667MHz PowerPC processor has been in short supply from chip manufacturer Motorola, due to high demands for the 733MHz chips.
