There are also a range of applications in the military and security industries.
Graphene and, more generally, carbon nanotubes are exciting because they have something-for-everyone. Silicon, plastics, water are examples of molecules or structures that have also been spun into important applications for just about every vertical. I suspect we'll seem carbon nanotube products explode over the next 20 years just as plastics did over the last 40. The article focuses a bit on whether graphene can rep…
In all seriousness, though, I think we're at a point with graphene comparable to the earliest days of the integrated circuit. We can imagine faster and smaller adding machines, but we can't quite yet imagine an IBM PC running VisiCalc. And the iPhone isn't even science fiction yet.

I hate to be that guy but: "megaton |ˈmegəˌtən| noun a unit of explosive power chiefly used for nuclear weapons, equivalent to one million tons of TNT"
You're being that guy. Plus, you're wrong. Mega- is a standard SI prefix, and the use of "megaton" to denote one million tons is entirely correct. Yes, it's also true that "megaton" has a second meaning. This fact does not invalidate its other meaning. In fact, if you bother looking this up in actual dictionaries, you'll find that the normal mass definition is often listed first, and the explosive definition is liste…
In any case, I am glad I learned something new today!
Optical computers, genetic catalogs, nanorepair modules--forget all of that. It's when you see a megaton of steel suspended over your head by a thread the thickness of a human hair that you really find God in technology. * Anonymous Metagenics Dockworker - MorganLink 3DVision Live Interview

I want clothing embedded with sheets of Graphene. Imagine the protection! I ride a motorcycle, which is one of the most dangerous daily activities one can do, and something that exhibits these properties could save me a lot of pain in wearing armored gear etc. There are also a range of applications in the military and security industries.

If IBM can make a 150 GHz graphene transistor, why does Dr Phaedon Avouris, of IBM, say that it cannot replace silicon? Isn't clock frequency a measure of the transistor's ability to turn on and off quickly?
There's so much more than clock frequency. The place silicon shines isn't so much it's material properties for producing individual switches - they're good, but there's better out there. It's the raw manufacturability that silicon has. It's by far the easiest material to work with. It's abundant, cheap, and easy to obtain. It's got properties that lend it to easy junction doping and easy annealing. It's easy to depos…

Wouldn't it be correctly called a "megaton ne ", as SI prefixes aren't typically applied to imperial units?
But (Sid Meier's Alpha Centauri) is an American game and it could actually refer to a non-metric megaton
