[M3devel] Linux/ARM? Android?

If you use qemu, this might be useful: http://free-electrons.com/community/demos/qemu-arm-directfb/

I'm currently looking at some cheap laptops (around $100) which have ethernet plus screen, keyboard, battery, etc which would work well as hosts. Just trying to find one that runs both Linux and Android.

Thanks. I'll give qemu a go as well.
Hey, maybe we can get mips also. (there's decent modern mips/linux hardware now, Chinese laptops)
