As I said before I think sometimes it all depends on what salesman gets to you first, and the education level of the consumer. If the EC can get the job done, the consumer might be left standing there saying "well, there's no turbine salesman in sight and I don't have time to look for one".
I would consider that the key area where the EC will surpass the turbine is in the sales push, especially if the EC can get the job done.
