The iPhone 6 and 6 Plus drove Apple’s most extraordinary quarter ever, with the company’s position in the smartphone market improving on all fronts: explosive growth in China, rising market share in the US and a rising average sales price.

By contrast, iPad sales continued to decline in spite of the iPad Air 2’s release, suffering from cannibalisation by the phablet-sized 6 Plus and saturation in developed markets. Apple has a strategy to revive sales, which may bear fruit later in the year.

A slate of new products is coming this year, led in the spring by Apple Watch. The question is, will Watch be a significant new source of profit or just a way to protect the iPhone’s dominant position in the smartphone market.

Happy Birthday iTunes! It is just over a year since Apple launched iTunes and the media continues to talk up the second coming of the music industry, whose saviour appears in the form of affable Steve Jobs. iTunes sold a total of 70 million tracks online in its first year, well below its target of 100 million, but a respectable showing, especially since it spawned a small flock of competitors determined to out-sell iTunes.
