The continuing fall-off in demand for personal computers has hit the three AIM Alliance members, Apple, Motorola and IBM.

Apple shares closed on Friday at a low of $15.063 – just three months ago they were valued at $58.875. Motorola and IBM shares prices closed on Friday at $19.20 and $97 respectively. This compares to a three-months-ago high of $33.938 and $119.125.

The results follow last week's profit warnings from Apple, Motorola and Intel. Intel, Dell, and Adaptec’s share values also plummeted, with a slowdown in demand for personal computers being blamed for the financial losses.

Software manufacturer Adobe, however, remains unscathed – enjoying an increase in share value from $66.938, to Friday’s close-figure of $68.375.
