Windows RT is obviously not doing as well as it could be. It was a complete no-show at this year's Computex, and Microsoft just took a $900 million hit related to unsold Surface RT inventory. Recognizing these facts, Asus Chairman Jonney Shih told AllThingsD that the company would be focusing mostly on Intel-powered Windows machines in the future as Windows RT, in his view, "is not very promising." As the report notes, this doesn't completely rule out future Windows RT efforts from Asus, but we wouldn't recommend holding your breath.

Asus was one of the few PC OEMs to give Windows RT a try late last year when the software launched alongside the x86 version of Windows 8. App ecosystem aside, we were mostly impressed with the Tegra 3-powered VivoTab RT convertible. Good hardware hasn't been enough to save Windows RT for other OEMs, either—after launching the Windows RT-powered Yoga 11 last year, Lenovo recently followed it up with an Intel version of the same laptop. Lenovo no longer sells the Yoga 11, Dell has heavily discounted its XPS 10 tablet, and Microsoft has cut the price of the Surface to $349 in recent weeks. In short, it looks like the writing is on the wall for Windows RT, barring some minor miracle.

While Windows RT didn't pay off for Asus, the company has found some success in its Android phones, tablets, and convertibles. Its second Nexus 7, developed in partnership with Google, was unveiled just last week, and the company hopes to bring its smartphone line to US shores in 2014.
