Acer, the world's third-largest PC vendor, and AsusTek are among Taiwanese computer companies that are developing or assembling up to 10 tablets for foreign makers, said Li Chang, an executive of the Taipei Computer Association. He did not identify the other producers.
Acer and AsusTek are expected to display tablet PCs at the Computex show in Taipei on June 1-5, Li said.
Officials at Acer and AsusTek declined comment. But Taiwan's Economic Daily News quoted unidentified sources as saying the two firms will launch tablet PCs in the third quarter this year with a price tag below $400.
Apple Inc.'s iPad tablet computer hits U.S. shelves on Saturday and international releases are planned for later in April. The iPads will connect to Wi-Fi networks and cost $499, $599 or $699, depending on the data storage capacity.
A Taiwanese research firm, Topoly Research Institute, said Tuesday tablet PCs might cut into shrinking sales of mini-laptops known as netbooks, a market dominated by Acer and AsusTek.
By 2012, sales of tablet PCs could reach 50 million units worldwide, surpassing the figure for netbooks, Topology Research said.
Meanwhile, although Apple's iPad tablet computer hits U.S. shelves on Saturday, customers who want the new touch-screen gadget shipped directly to them will have to wait a week. The iPads going on sale will connect to Wi-Fi networks only and cost $499, $599 or $699, depending on the data storage capacity.
Another challenge facing Apple is how to convince existing Mac, iPhone, and iPod users to actually buy another device, according to a new report from research group NPD. Only 18 percent of consumers surveyed responded as being extremely or very interested in owning an iPad, the survey found.
