Having unveiled its Windows 8 notebook/tablet convertible mobile device at CES 2013, Chinese tech firm Lenovo reportedly plans to expand its IdeaPad Yoga family to also include Intel-or ARM-based convertibles running on Android OS in the first half of 2013.

Industry sources have told DigiTimes that Lenovo originally planned to launch a Medfield-based tablet based on Android in the third quarter of 2012 but delayed the project due to continual rollouts of new iPads and Windows 8/RT tablets as well as a proliferation of low-priced Android tablets.

"Lenovo's planned offerings will target the Android tablet segment, meeting Intel's previous commitment to rolling out Android-based tablets through joint efforts with Lenovo," the sources told DigiTimes.

Lenovo already makes an Android-based tablet, the IdeaPad A1107, which is marketed as a budget device at just 7-inches with a 1024x600 display resolution.

The new convertibles are part of the tablet/notebook hybrid Lenovo produces - tablets which feature keyboards attached via 180° hinges. Those hinges allow Yoga systems to fold flat, with their screen and keyboard facing outwards so the device can be used as a tablet; or folded in to turn it into a stand-alone computer.

The first such devices from Lenovo are based on the Windows 8 system. The company unveiled its Windows 8 IdeaPad Yoga 11S notebook/tablet convertible at CES 2013 in Las Vegas last week.

The Yoga 11S is powered by an Intel Core i5 processor running Windows 8 on an 11.6-inch HD IPS panel with 10-point multitouch. It's slated to hit U.S. stores in June, priced at $799.
