Intel has set ambitious targets for the number of ultrabooks it hopes will sell this year, part suppliers understood late Wednesday. Supposed internal roadmap details passed on to Digitimes had between 20 million to 30 million ultrabooks shipping in 2012. That number would double or triple in 2013, according to the claims, as the supply chain would be truly ready for mainstream adoption, such as reinforced plastic to emulate the rigidity of metal without some of the cost.
