Asus company president Jerry Shen has detailed a raft of tablets that it plans to begin launching from December this year. The tablets will ship in a range of sizes including, seven-, 10- and 12-inches and should be powered by ARM-based processors or Intel Atom chips depending on the OS. The first to hit the market will be the Intel- and Windows-powered 12-inch EP121 tablet that also included product development input from Microsoft, which added enhancements to touch control and the interface.
