In the first 12 months of sales, Apple sold nearly 14 million Watch devices, according to shipment estimates from research firm IDC. (Apple doesn’t disclose Apple Watch sales or its revenue from the device.) I have written before about why Cook’s iPhone yardstick for the Apple Watch is a dubious comparison. And in a partial third year for the Apple Watch -- the nine months ended Dec. 31 -- Apple sold 14 million Watches, IDC estimated. Are those credible ways to measure people’s happiness with the Apple Watch, or the success of the device in general?
