Interesting, I wonder how it runs Android apps. As far as I know, most (all? none?) are compiled just for ARM. Does Chrome OS emulate Android on ARM? I can't imagine that'll be remotely fast (which perhaps explains why it can't run on some chrome books)

Some Chromebooks are ARM, probably more on the way. Some Intel Chromebooks do indeed have enough processing power to handle emulation, so I think what will happen in practice is that apps lacking x86 binaries will be translated via libhoudini.
