With the sale of Nokia to Microsoft in the intervening year and the disruption that this inevitably caused, the rise in sales is reassuring. In fact, Microsoft generally had a very good quarter, see the executive summary here. Devices and Consumer revenue grew 47% to $10.96 billion, while Commercial revenue grew 10% to $12.28 billion.
9.3 million Lumias in a quarter (plus, no doubt a million or two from other licensees, including the new ones, a contribution which will only grow and grow) should be put in context against typical Apple iPhone sales of 30 million or so (i.e. only a third as many as iPhone shipments) and typical Samsung Android sales of up to a hundred million per quarter. Worldwide smartphone market share for Windows Phone is still somewhere between 3 and 6% (depending on how you define 'smart', as always), though of course higher, up well over 10% in some markets. Still, Windows Phone is very much still in the game, especially with the Windows 10 thrust/unification happening over the next 12 months.
