If there's one downside to powerful computers, it's that they're too big.
Luckily, that's about to change. At least, if IBM has anything to say about it.
Last month, IBM held its flagship conference, Think 2018, where the company unveiled what it claims is the world's smallest computer. They're not kidding: It's smaller than a grain of salt.
But don't let the size fool you: This little fella has the computing power of the x86 chip from 1990. Okay, so that's not great compared to what we have today but cut it some slack – you need a microscope to see it.
