They have. But they aren't the only reason that macs are doing well. Apple was the most profitable PC maker even before the iPhone was introduced in 2007. It was selling the most >$1000 computers even in 2006. There is a very clear event when Mac's popularity shot up. It was right after the transition to Intel. The ability to run Windows as a fallback made the switching process far less risky, enabling the Mac's rise.
