Dunno why they made this piece discuss Apple so much tbh. The entire wearable market only ever really existed in Marketing's head and is rapidly collapsing into niche bling for fitness fanatics, regardless of if it's iTat, Droid or Microsoft running on it.
A grand total of 4 million sales, half of them for devices which ultimately amount to accessories for the iPhone (with iPhones themselves a very small and shrinking minority of the smartphone market outside the US) is a sure sign that wearables of any stripe are about as must-have as a monogrammed walrus polishing kit.
