Wall Socket PC
This Wall Socket PC is pretty interesting. It's all the guts of a computer in one small unit designed to be used as a home PC with standard power. It uses an AMD RISC processor, and can come with up to 64MB of flash memory and 128MB RAM.
Why does this interest me? Well, like the gumstix, this thing is tiny. I could see it being useful for a wearable computer, even though that's not what it was designed for.
