Must of us (pragmatic programmers, hackers, entrepreneurs) are always looking for resource efficiency, we're always looking for DRY. The way we manage our devices is broken, why do I need to install 4 times every single app in my ipad, android phone, PC and laptop? Why do I need 4 different processors, why do I need RAM distributed through all my devices?
I think this is a great idea, and we hackers would love it. But this solution may have some downsides though. I think there must be a single OS for both PC and Mobile, it just should change its interface, and I'm not sure if the power of my phone would be enough for a PC experience yet, anyways I hope this idea come to reality soon!
