Asus,  CEO Jerry Shen spoke to the Wall Street Journal, and repeated that “Windows RT has not been very successful” and said that the company took a writedown on its stock of RT tablets.
He also said that, from now on, ASUS will solely make Windows 8 devices that run on Intel / x86 processors, due to the backwards compatibility with Windows software offered by those products.

The Microsoft offering with 2 different types of Windows was just too confusing and limited.  Asus is not the only company to suffer huge losses due to poor sales.
