Does anyone have old and new Airs, same CPU and Memory, where the old one has a runcore SSD, to compare for performance? It would be even better to see the results with the old MBA (or eventually both) using coolbook to prevent throttling. In other words, some like-for-like benchmarking would be great. I don't doubt that the new one (Rev D?) is the faster of the two, as it has a better graphics chip for a start. However, I am trying to decide if I should throw a Runcore SSD in to my RevC, or hold out for a totally new machine.
