Android on the PC?

Asus, for instance, offers the Transformer Book Trio, which it bills as the world's first 3-in-1 notebook, tablet and desktop PC.

That device is a dual-boot Windows 8 and Android laptop running Windows on an Intel Core i5 or i7 processor and Android on an Intel Atom. The screen detaches to become a tablet, and the Trio plugs into an external monitor to serve as a desktop PC. The tablet runs Android apps that are on users' smartphones.

Acer, meanwhile, offers the DA241HL, a 24-inch all-in-one desktop PC running Android.

In March, Intel released a pre-alpha build of an optimized version of Android Jelly Bean 4.2.2 that would run on an x86 processor. There's one catch, though: Apps written for ARM-based devices will need to be recompiled for x86 or emulated.
