Engadget posted a story that China Times is reporting that Microsoft is only letting an elite few companies build Windows RT tablets in order to focus its research and development resources.

It asked three chipmakers to pick up to two OEMs to bring inside the tent, with NVIDIA grabbing ASUS and Lenovo, TI snagging Toshiba and Qualcomm selecting Samsung and HP. However, the latter company dropped out of the program to concentrate on x86 machines, so Dell's currently jockeying to take its place.
