For most of its lifespan thus far, Android has been a platform most familiar with processors based on ARM architecture. Aside from a few examples like Google TV, few products have been based on the x86 set of processors, but one group — going by the appropriate name Android-x86 project — already has a functional build of Android 2.3 (Gingerbread) ready for Intel’s chips. Keep in mind, this comes before any current ARM handset, including the Nexus One, even receives an update to the latest version of Android.
There are still a few hang ups. Ethernet, 3D, and mouse support are still in the works. Sound and Wi-Fi are a go, however. More info can be found at the Android-x86 link below.
