An unconfirmed report from industry watcher DigiTimes suggests Apple may have been forced to reduce its first-quarter iPad production by as much as 50%. The report cites upstream component makers in claiming Apple’s first-quarter iPad 2 production volume has been revised down from between 400,000 and 600,000 units to between 300,000 and 400,000 units. The new lower production targets are allegedly the result of display panel shortages and last-minute specification changes Apple made ahead of production. Earlier rumors suggested Apple’s spec changes might delay the launch of Apple’s iPad 2, but DigiTimes claims the tablet is still on track for a second-quarter release. Apple is expected to unveil its next-generation iPad tablet at a media event next week.
