Prior to the M-P, my digital M was an M9. I went with the M-P because the deal Leica offered was better, but also because the sapphire LCD cove is more durable, the extra buffer is a plus, and I like the starker styling. It was worth the extra money ... Since I don't get the opportunity to buy new Leica new very often, might as well go for the gusto and enjoy it.
