This is a very interesting thread with a variety of good points made. I just have some random thoughts:
1. I question whether the sales data is accurate, but oh well.
2. How is a product that has been available for sale for about 2 months considered a failure?
3. What were the sales goals of this device? If we don't know what the sales goals are and we don't know how many units or what revenues the device brought in, how can we classify it as a failure?
4. Why are people comparing (possible) Apple Watch sales to iPhone sales? Isn't that an "apples or oranges" comparison? Wouldn't it make more sense to compare the Apple Watch to competing, similar products. Here's an analogy. Honda makes cars and they more recently started making airplanes. Should people compare sales of the Honda Accord to the Honda Jet, or should they compare sales of the Honda Accord to the Toyota Camry?
I'm pretty critical about things apple co does, but I agree with all your parts.
I don't think we can call it a bust. you're points are all extremely valid. We will have to see when real numbers come out (dollar $s). For all we know, Apple foresaw only selling ~4m in the first year and that is their target.
if they hit their target, it's not a failure is it?
