Apple Watch became known as a black hole within the company, the WSJ's sources said, as it continued sucking in resources for four years despite all the failures during testing. Its development slowed down once the company realized that a health-focused watch that meets its standards will be very hard to build at this time. The lineup of watches due out in April are a lot different from the original one Apple envisioned and are more of an iPhone companion with a much simpler pulse monitor and pedometer.

Still, the company's expecting to sell a ton, reportedly ordering around 6 million units from its Asian suppliers just for the first quarter. Half of those are the entry-level Apple Watch Sports, while the mid-tier stainless steel model makes up a third of that number. As for Cupertino's original vision, well, there's always a chance that we'll see it come to life in the coming years. The company has a good track record of substantially improving its devices after a debut model appears -- the first iPhone didn't have 3G.
