Windows 8 has been out for 2 years now? That's news to me.
They're probably including the Developer Preview in that figure.
And how is lowering the price of a windows licence to put them on a level playing field to Android, thereby providing a choice of OS to the consumer a bad thing?
It's not, directly. The issue is the way Microsoft has litigated to drive up the cost of Android, with it actually costing manufacturers more to ship with Android—a free operating system—than to pay the licence fee for Windows Phone. A lot of the time it relates to ridiculous patents that should never have been awarded but take years to challenge. It's hard for smaller companies to defend themselves against such litigation and they usually end up settling at an excessive rate. Microsoft then uses that position to try to pressure manufacturers into including Windows Phone. I just don't have any respect for such business practices.
