Essentially, right now it is really really difficult to work with graphene on an industrial scale.
If you want to work with it in the lab, you get yourself some graphite (essentially pencil lead), some scotch tape, some solvents and you're done. It is dirt cheap and, given a good microscope and a steady hand, not too difficult to work with.
But of course this is no way to work with it on any larger scale. You want to be able to produce a certain amount of it, reliably and precisely. No flaws in the graphene crystal. No multi-layer graphene (which in fact is one of the toughest things to avoid).
This is all really difficult right now.
The situation was similar for transistors, if you recall: the first solid-state transistor was invented in 1947 (by 1956 Nobel prize winners John Bardeen, Walter Brattain and William Shockley), but it took until the 1960s for ICs to take off (Jack Kilby, 2000 Nobel prize winner, is usually pointed out as the culprit). It took until 2004 (!) for the first single-layer graphene to be isolated (by 2010 Nobel prize winners Andre Geim and Kostya Novoselov). So expect the first industrial application of graphene somewhere around the end of this decade, and some patent wars around 2019-2025, and then a Nobel prize for the inventor of whatever industrial process we will be using, around 2040.
