First, the impressive sales numbers: Macs make up 33% of Apple's revenue — that's $22 billion in a year and a 27% growth over the previous year. Apple claims that Macs now account for one in five PCs sold at retail in the United States and that they have an installed user base of almost 50 million people across the globe. Macs outgrew the market four years in a row.
Cook also took the opportunity to boast about the success of Apple's retail stores. In the past quarter, Apple's 318 stores have received 75 million visitors and sold 2.8 million Macs. Half of those sales were to new Mac users. The company just launched its second store in China and claims that the Chinese stores are its busiest.
Apple has implied in the past that the success can be attributed to developer support. Whether that's lip service or not to say that is beside the point; developer support is indisputably essential for the success of any computing platform. To that end, Apple bragged that it has 600,000 registered developers, with 30,000 new ones each month.
