Actually, I think diamond is getting much cheaper. It's becoming much more integral for satellites and extremely small electronics because of their susceptibility to radiation. http://news.vanderbilt.edu/2011/08/nanodiamond/

The first thing I'd wonder is what the susceptibility to radiation is for spintronics. The paper "Spintronics: a new paradigm for electronics for the new millennium" says that it is as hardened as the silicon. So then I'd question how hard the graphene is and found a couple of papers about that: Unzipping and folding of graphene by swift heavy ions, Effect of electron-beam irradiation on graphene field effect devices.

Researchers out there realize the problems popping up with silicon and are working to find the solutions. It's a really cool time to be in material sciences, physics and/or electrical engineering.

Yeah, but good luck doping it n-type.
