Graphene is an amazing material but I think it suffers from the same problems as nanotube electronics - it's very hard to get the nanotubes to be positioned where you want them and connected in the topology that you wish. Geim's group has in the past used "exfoliated" graphene (basically the graphene is just peeled off with a bulk sample with scotch tape) And made some amazing discoveries that connect solid state physics to relativistic quantum field theory because of graphene's unique band structure. But for making electronic devices where you would want to pattern ~10^6 transistors, the exfoliation process is very hard to control and seems unlikely to scale well. When someone can produce a graphene sample the size of IC die call me. Still it does seem to have a lot of theoretical advantages over silicon, GaAs et. al. (especially the possibility of ballistic conduction)
