Memristor circuits lead to ultrasmall PCs. Intel and AMD unleash massively multicore CPUs. Samsung TVs respond to your every gesture. These and other developing technologies will fundamentally change the way you think about--and use--technology.

Illustration: Randy LyhusThe Next Big thing? The memristor, a microscopic component that can "remember" electrical states even when turned off. It's expected to be far cheaper and faster than flash storage. A theoretical concept since 1971, it has now been built in labs and is already starting to revolutionize everything we know about computing, possibly making flash memory, RAM, and even hard drives obsolete within a decade.

The memristor is just one of the incredible technological advances sending shock waves through the world of computing. Other innovations in the works are more down-to-earth, but they also carry watershed significance. From the technologies that finally make paperless offices a reality to those that deliver wireless power, these advances should make your humble PC a far different beast come the turn of the decade.
In the following sections, we outline the basics of 15 upcoming technologies, with predictions on what may come of them. Some are breathing down our necks; some advances are still just out of reach. And all have to be reckoned with.
