There’s a rumor being perpetuated by Daring Fireball that Microsoft only sold 503 KIN devices. Many other sites are picking up this posting as though it were true. What I find interesting is that the KIN registers its Facebook app on Facebook, where anybody can actually see the total number of monthly active users of the application. The KIN Facebook app is only available on KIN devices and can only be used by people who have KIN devices. So how many people are actually using KIN devices that are connected to Facebook? 8,810 as of right now.
If you see anyone repeating the 500-KIN-sold rumor, feel free to link them to the truth right here.
