The rumored Amazon tablet is being made by contract manufacturer Quanta and should be available by the end of the year, part suppliers said Monday night. It would make as many as 700,000 to 800,000 of the tablets a month and could ship them as soon as the second half of the year. Digitimes was told Amazon would have a unique tie-in with its usual e-paper supplier: although E Ink would supply some display components, it would be giving just the fringe field switching technology used in LCDs and a touchscreen layer.
