The state of "molecular electronics"

For those interested in the history and current state of "molecular electronics", I refer you to the latest focus issue of Nature Nanotechnology.  Good news for those without subscription access - some good articles are available free of charge:

• Mark Ratner has an historical perspective on the field here.
• Emanuel Lörtscher discusses the challenges of making an actual technology out of these systems. 
• A variety of experts (including me) weigh in with blurbs about where things are and where they are going.
• Sri Aradhya and Latha Venkataraman present an excellent up-to-date review of the field, emphasizing the evolution of measurements beyond just collecting current-voltage characteristics.
