According to a new report from industry watcher DigiTimes on Tuesday, Amazon has placed orders with manufacturers to build its first tablet PC. The report claims Taiwan-based Quanta Computer has received orders for between 700,000 and 800,000 tablets from Amazon, and the finished devices should begin shipping in the second half of this year. Earlier rumors suggested an Amazon tablet would launch this summer, so the timing of this new report further supports those claims. Amazon has built several successful devices with tablet-like form factors — it’s Kindle eBook reader is the best-selling product of all time on Amazon.com — but this would be the company’s first device to venture beyond eBooks. Amazon’s tablet, which is said to be based on the Android platform, will like showcase several Amazon products and services such as the Amazon Appstore, Amazon’s digital music store and the company’s new Cloud Drive digital music locker service.
