Is it possible that Android runs on x86 computers?
x86
It looks like someone is working on this ... http://www.androidx86.org/
Yup, there is already an image that you can install on Eee .
Another way, of course, is to run the Android emulator. The Android SDK comes with an emulator that can run all the different versions of the OS. It uses qemu to emulate the ARM processor architecture.
