Industry watcher DigiTimes on Friday reports that Apple is still on track to have roughly 40 million iPad tablets built and shipped in 2011. The site stated yesterday that Apple plans to ship up to 6.5 million iPad tablets in the first quarter of this year, and now it’s on record as saying second-quarter production will be ramped up to a staggering 10-12 million units. According to the report, Apple ordered approximately 2 million first-generation iPads in January before kicking off iPad 2 production. Shipments of the iPad 2 are expected to come in around 3 million units this quarter. The second quarter will see between 10 and 12 million units built as noted, and DigiTimes’ sources suggest Apple’s manufacturing partners will ship between 21.5 and 24 million units in the second half of the year. The report does not speculate on whether or not second-half shipments might include the iPad 3, which could launch ahead of the holidays this year according to rumors.
