That's a good question. The number of iOS devices sold is stagnating. Mac numbers (in units sold) are falling precipitously (-14%). Revenue has grown because they were able to raise prices and because they sold more services. I think the room for price increases is limited. So it's all down to services now. I think there is room for growth given their high income customer base, but it will change their business model in ways that will spark many debates on here.
