So I'm one of the 0.5% using Windows Mobile 10. I enjoy the OS, and prefer it to Android or the other mobile OS that people seem to like. I can see why the numbers are dwindling though. Worldwide, IOS is small and on expensive proprietary hardware. Android - though it is not as secure as IOS or Windows - is easily consumed whether one buys a US $2,500 Huawei Porsche Mate 9 (http://www.welectronics.com/gsm/HUAWEI/HUAWEI-Mate9-Porsche-Design.HTML) or an off-brand devices for under US$50. Microsoft really shot themselves in the proverbial foot changing from Windows 7 to Windows 8 then to Windows 10. I see what they hope to achieve with Windows 10 and the unified platform but think it will be more of a change in a few years.
