The Acer Computer International Ltd arm of Acer Inc reckons there is a big unfilled need for a low-cost personal computer in the markets it serves in Africa, the Commonwealth of Independent States, the Middle East and Asia, and in the second half of the year, it plans to launch a basic $1,000 machine to meet that need. It sees such a machine being used as an educational tool and as an Internet access terminal. The company is not saying which processor it will use, but hopes to sell 200,000 in the first year. Acer in Singapore told Reuter that it sees Hewlett- Packard Co and Compaq Computer Corp as its toughest competitors.
