I don't get the impression that more than a couple people here understand what this article means. In short, it doesn't really mean much. This is like the earliest stage of development, you have no idea how many things get developed like this that you will never see again. See carbon nanotube high def TVs for an example
And on that note, IBM must know something we don't about the price point of graphene, because for them to be dev'ing with graphene instead of with carbon nanotubes (kind of but not exactly a rolled graphene and much cheaper and way more interesting properties) is kind of confusing
The real hurdle for both graphene or CNTs is the difficulty of bulk production. With nanotubes growing/cutting them to an exact length and diameter (which effects metallic vs semiconducting properties) and placing them somewhere is remarkably difficult, and graphene, well graphene is simply one of the most expensive materials known to man.
Anyways though, still cool to see people messing with the funky carbons. There has been speculation on what you can do with these super molecules for a long time, and I am glad to know that the lack of market realization for either of them hasn't killed development or interest in either.
