Hey Stuart, I am interested in what sold you on the Phi. My cursory look suggested that using the Phi in Intel's offload mode (which preserves the scalar performance) was not much easier to program than writing in CUDA ... and that using the Phi as a standalone processor while a programming convenience suffers on scalar code. Even that programming convenience is limited by the fact that you have to think both in terms of vectors and threads.
Also, the speed ups I have seen generally seem modest, understanding that GPU performance hype is exaggerated. Hearing what you like would be interesting.
