AppleIf the upcoming iPhone 8 is as commercially successful as some predict, Apple may have 1 billion mobile users by the end of the decade. The iPhone 8 release is set to "unleash pentup demand," with annual unit sales reaching 270 million in 2019, according to research analysts at Credit Suisse. Reaching those sales figures would put global iPhone users in the neighborhood of 970 million by the end of 2019. "We remain convinced that the iPhone product cycle will be significant in terms of driving multi-year unit growth," the Credit Suisse report noted.
