Installing OS X on non-Mac hardware is a violation of Apple’s licensing terms. But it’s interesting to see that it’s easier to install the Mac operating system on unsupported hardware than it is to install the open source Ubuntu Linux distribution. At least for now. As CrunchGear and other sites have pointed out, Ubuntu 8.04 Hardy Heron hangs when you try installing it on an MSI Wind notebook.
I suspect this is a temporary issue, as Canonical is currently working on Ubuntu Netbook Remix, a custom version of Ubuntu optimized for devices with small screens and Intel Atom CPUs. While MSI will eventually offer a Linux version of the Wind notebook, it will be running SUSE, not Ubuntu. But I suspect the Ubuntu/netbook hacking community will figure out a way to get Ubuntu up and running soon after the laptop is released.
Update: Paul at MoDaCo has posted step by step instructions for installing OS X on an MSI Wind, Medion Akoya Mini or Advent 4211.
