I think the V9 appeals mostly to people who want to learn about mining, but don't want to invest thousands of dollars up-front. If I were just getting started, the V9 would be worth the money just so that I can make sure I know how everything works before purchasing a more efficient (expensive) miner. Besides, lots of people don't mind using these as glorified space heaters that earn a little money to offset the electricity. I have a neighbor using some D3s for that purpose specifically.
