a16z Podcast | The Micro and Macro of Mobile

App Store Economics and Platform Comparison

• Developer Payouts and Revenue Disparities
  • Apple reported paying out $20 billion to developers in a single year, representing a 100% increase from the $10 billion reported a year prior.
  • Google reported paying out $5 billion to developers over a 13-month period since their previous data disclosure.
  • Revenue per User Metric: iOS generates approximately four times the revenue per user compared to Android, based on an estimated 500–600 million iOS users versus 1 billion Android users.
  • Growth Trajectory: While Android user count is projected to grow from 1 billion to 2–3 billion, this expansion is expected to be driven by lower-average-spend demographics in markets like China (non-Google Android), rather than a proportional revenue increase.
  • Market Fragmentation: Developers face complex decisions regarding platform suitability due to Android's hardware fragmentation and the potential lack of "unblocked" platform opportunities compared to iOS.

Tablet Sales and Consumer Behavior

• iPad Sales Dynamics
  • iPad sales have remained flat for the last year when analyzed via trailing 12-month revenue, smoothing out product launch spikes.
  • The flat sales figure does not indicate a shrinking user base; rather, the installed base continues to grow as existing units are retained for longer periods (3–5 years) similar to personal computers.
  • Installed Base Estimates: The number of iPads in use has likely doubled from Apple's stated 80 million to approximately 180–200 million devices.
  • Purchase Drivers: Approximately 50% of iPad sales go to new owners rather than upgrades, confirming the device functions as a household appliance rather than a frequent consumer electronics replacement.
  • Upgrade Perception: Technical specifications (e.g., Retina displays, weight reduction) are perceived as negligible by consumers, reducing the incentive for frequent hardware upgrades.

Enterprise Adoption and Workflow Transformation

• Apple-IBM Strategic Partnership
  • The deal addresses a critical barrier in enterprise tablet adoption: the need for professional services, consulting, and process redesign rather than simple device distribution.
  • Productivity Misconception: A common narrative assumes tablets cannot replace PCs for tasks like Excel or PowerPoint; however, the partners argue that workflows are shifting from manual data aggregation to real-time web dashboards and mobile-native processes.
  • Implementation Challenges: Enterprise deployment requires "hand-holding" and security protocols, contrasting with the consumer model where users self-configure devices via app stores.
  • Operational Shifts: Mobile devices are displacing legacy desktop workflows in sectors like car rental and logistics, where field workers previously relied on fixed PCs or typewriters.

Macro Market Opportunity and Multipliers

• Device Volume and Reach
  • The global market now includes 2–3 billion iOS and Android devices, compared to a stagnating or gently declining 1.6–1.7 billion PC market.
  • PC Equivalents: Adjusting for shared usage and corporate security restrictions, the effective "personal computer equivalent" is estimated at 700–900 million, far lower than the total hardware count.
  • The "10x" Market Effect: The transition from PCs to mobile represents a 5x to 10x increase in market opportunity, driven by the convergence of:
    • Volume: More total devices.
    • Usability: Mobile interfaces require less "computer literacy" than PCs.
    • Sophistication: Smartphones integrate cameras, GPS, microphones, and tilt sensors, offering input methods PCs lack.
    • Location: Devices are portable, enabling use cases in-store, in-transit, and in the field, unlike fixed-location PCs.
    • Access: Mobile payment methods and internet connectivity are more accessible globally.
