It's interesting to see people talking about smaller and smaller boxes because. at the moment, the chip manufacturers seem hell bent on building chipsets that run hotter and hotter.
When they cram them into a small box there's not enough air flow and the things just cook.
And as for plucking the Internet out of the air - that's not as whimsical as it might sound. A small electricity provider here in Australia and one over in the eastern states in the USA have both been experimenting with providing internet access via power lines at speeds that are truly staggering.
I don't know what is happening in the US but here in Australia they are just about ready to go commercial with it.
Still it's not anywhere near as good as a walk on the beach at sunset with a beautiful woman - except I now have a lot of sand under my desk
