Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
iOS Surges Past 60% Share of Mobile Web Traffic
Net Applications Mobile/Tablet Top Operating System Share Trend (Nov '09 – Oct '11)
Apple's dominant share comes from its strong position across all three mobile device segments with the iPhone, iPad, and iPod touch. Google's Android operating is also seeing very strong growth in line with its rapidly-growing device sales, but Android's popularity has primarily been restricted to smartphones.
On the PC/Mac side, Apple is also continuing to increase its share of Web traffic, reaching 6.94% in October, a healthy increase of nearly half a percentage point over September and up nearly a percentage point and a half since April.
