Apple's phenomenally successful iBook sales have lent advantage to Apple supplier Alpha-Top.

Taiwanese manufacturer Alpha-Top makes iBooks for Apple. The supplier now expects its portable computer shipments will exceed one million units this year. 85 per cent of the company's notebook business comes from Apple.

Local Taiwanese IT-journal DigiTimes reports that Alpha-Top shipped 150,000, 280,000 and 400,000 units respectively in the first three quarters of this year. In October, the company shipped 100,000, and 100,000 and 70,000 unit shipments are expected in November and December.

Apple's iBook accounted for 75 per cent of Alpha-Top's 320,000 units shipped in 1999, and 92 per cent of its business in that sector in 2000. Elitegroup Computer Systems acquired Alpha-Top in August this year in a deal worth $234 million in shares. Elitegroup hoped to gain access to the broadening market for portable computers.
