Either my computer is too small or my pants pockets are too large, but the Asus EeePC my employer purchased for me fits in my cargo pants pocket.
So “there’s a computer in my pants” might sound like a creepy pickup line at a tradeshow, but it might also be true.
If you want a tiny computer shipped to you in any reasonable amount of time, you might want an EeePC instead of an OLPC, since they seem unable to deliver them to “paying” customers. I’ve actually had a chance to compare the two side-by side. I’ll post later with my observations, pictures and video featuring a cat walking across both keyboards.
