I'm glad researchers are making progress on figuring out how to surpass the limitations of silicon. But best to take PR articles like this with a grain of salt of course. "Carbon nanotube transistors should be able to perform five times faster or use five times less energy than silicon transistors, according to extrapolations from single nanotube measurements." Well, that's the real trick isn't it? Other factors will come into play when you scale from one transistor to a billion. Heat dissipation, physical size, and practicality of manufacture are all open questions. This technology is still many many years away.
