As crazy as it seems I seem to agree with Dave, since Sailfish itself, was meant to be exactly what Mer is, a distribution for manufactures to build there own UI and system onto top of, which is exactly what Mer is. There both the same thing more or less. Or did I miss something here? I thought Jolla was the actual OS with swipe, android layer etc.

I thought libhybris there by default is what Sailfish has over Mer.
