So years ago I remember there being a lot of hype about $100 laptops which would be great for developing countries and if I recall correctly, I think those projects were realized. However, over time cheap tablets seemed to have taken over and in the more recent years the tiny computer movement has taken off with devices like the Raspberry Pi. I was talking to a friend recently and he told me about Chip, a $9 computer. At first I thought I misheard him but he reassured me that it was correct so I had to look it up: http://getchip.com It is important to note that $9 only gets you the barebones unit, you'd probably want to spend a bit more to get some of the addons but still a promising deal. They have a portable version as well. It's pretty cool how far we're progressing. I've yet to tinker with any of those tiny PCs myself but I think I might get this one.
