I do currently use Windows Phones and i supply my staff with them(Lumia 1520's)i also use Surface pro 3's and Windows 10 on my Laptops.
But i will be moving away from the phones shortly as they are just not supported that well in every way.
As for the Edge/Chrome argument it was Microsoft and Google's decision to drop the support for the Silverlight plugin hardly Sky's fault.
That one statement at the beginning of your post shoes how short sighted you are,i hope your not in charge of a business or any decision within a business.
