This is an interesting development from the boys over at VentureBeat / Mobile-facts who spent their holidays compiling Android to run on an Asus EEE PC (don't you just love geeks?).
In the process of doing so they discovered all sorts of code documentation and what not that showed that whilst Google's Android operating system has been made available for mobile handsets it has also always been intended to operate on a wider range of hardware systems including NetBooks.
The potential here is for an open source operating system with applications, supported by advertising, that could work seamlessly across mobile, NetBook and other systems. Given that it's relatively easy to install alternative operating systems on everything from iPods to PS3 you can expect to see Android popping up all over.
