I would continue to take Slice Intellegence’s numbers with a grain of salt, but if Apple sells 8-9 million units in the first year (as Slice’s sales-per-day numbers suggest) I’d consider that a huge success. I never subscribed to the 20-40 million units number that many analysts were predicting. Remember, the fastest selling product in Apple’s history is the iPad and it “only” sold 14.8 million units in its first year. Why would anyone expect the Apple Watch to sell faster than the iPad?
