*shrug* There's also an x86 version of iOS - it's how the Simulator works in Xcode. But it's still mostly irrelevant given that this latest article was nothing to do with Android or iOS and solely about removing optical drives from the laptop and bigger devices.
@Pete> There's an x86 version of Android, which can be used to install it on a computer (there's a website dedicated to that, can't remember the URL.) It can also be run in a VM, and it's faster than the stock Windows Android emulator. (Although Intel now ships special drivers for that emulator that make it way, way faster... Actually twice faster than a S3 or something.)
