Episode Summary
Executive Summary: The episode ranges from technical follow-up on audio routing and headphone design to a long discussion of Apple’s financial results and what they imply about the future of the iPad, PCs, and new product categories. The hosts argue that iPhone dominates Apple’s business, the iPad is under pressure from phones and cheap tablets, and future growth likely depends on Apple finding a new major product line.
Main Topics: AudioBus, Inter-App Audio, and OS-level audio routing: They correct earlier misconceptions about AudioBus and explain that it used MIDI sysex and mock ports rather than network loopback. They argue Apple should expose better OS-level audio routing because third-party tools rely on private APIs and many apps need official support. Lightning-only headphones and headphone-jack replacement ideas: The discussion evaluates whether Apple could sell Lightning replacement cables for detachable headphones. The hosts conclude it is impractical because headphone-side connectors are not standardized enough across models, though Apple could potentially support Beats-specific accessories. Plasma burn-in / Destiny HUD follow-up: They revisit a prior issue where the Destiny HUD seemed burned into a plasma TV. After a year, the retention has mostly faded, suggesting the effect was not permanent but extremely slow to disappear. Pirate eye patches, dark adaptation, and testing vs. theorizing: They correct the popular myth about pirate eye patches and explain why the Mythbusters test worked: dark adaptation is driven by rod sensitivity as well as pupil size. The broader lesson is that some questions are faster and more reliable to answer by testing than by theorizing. Apple earnings and the meaning of iPhone ASP and margins: They analyze Apple’s earnings call, emphasizing that iPhone drives most revenue and that average selling price and margins strongly influence product decisions. They argue Apple’s choices often balance customer value against financial incentives like boosting ASP. The iPad's role in a post-PC world: A long debate centers on why iPad sales are declining. One view is that tablets are being squeezed by phones at the low end and laptops at the high end; the other is that tablets may still represent the long-term future of touch computing, even if Apple’s current iPad line has not realized that potential. Water resistance, durability, and the iPhone 7 rumors: They discuss whether the iPhone 7 may become more water resistant or even waterproof, especially if Apple removes the headphone jack. They expect Apple to keep improving sealing and toughness, but note that drop resistance remains hard because glass is still the preferred material.
Key Arguments: AudioBus was unfairly described as a network-based workaround; it actually relied on MIDI sysex and mock ports, which are built on existing system facilities. Apple should expose OS-level audio routing instead of forcing developers to rely on private APIs or app-to-app cooperation. A Lightning replacement cable for generic detachable headphones is unlikely to work well because headphone-side connectors are not standardized enough. The Destiny HUD burn-in was not truly permanent; plasma image retention can fade substantially, but it may take a very long time. The eye-patch effect works because dark adaptation involves rod sensitivity in the retina, not just pupil dilation. Testing can be superior to explanation when the question is easy to verify empirically. Apple’s iPhone business is so large that average selling price and margins matter enormously and can influence product decisions that are not purely customer-driven. The iPad is being squeezed from both ends: phones are bigger and more capable, while cheap tablets handle entertainment use cases. The iPad may still represent a future “touch computing” form factor, but Apple’s current iPad line may not be the company that fully realizes it. Water resistance is increasingly important because it solves real customer pain points, while drop resistance remains harder because glass is still desirable for feel and scratch resistance.
Data Points: iPhone share of Apple revenue: 68% - Cited from the Six Colors/earnings discussion to show how dominant the iPhone is in Apple’s business. Apple TV burn-in follow-up interval: 1 year - John set a calendar reminder for a year to check whether the Destiny HUD had faded. Eye recovery time for dark adaptation: half an hour or more - They cited an astronomy article explaining that bright light can wash out rod sensitivity for a long time. Harry's starter set price: $15 - Sponsor spot: razor, shaving cream or gel, and three blade cartridges. Harry's replacement blades price: $2 each or less - Sponsor spot describing factory-direct blade pricing. Squarespace discount: 10% off - Sponsor code ATP at checkout. Fracture discount: 10% off - Sponsor code ATP10 for photo prints on glass. Estimated iPhone average selling price: $691 - Mentioned while discussing why Apple is motivated to maintain or increase ASP. iPad sales trend: down sharply - Described qualitatively during the earnings and product-strategy discussion. Potential app ecosystem support change: iOS 7 - The Inter-App Audio framework was described as added in iOS 7.
Pivotal Quotes: "The iPad is the truck of the world of iOS and touch devices or whatever." — John Siracusa: Explaining his view that tablets serve narrower, heavier-duty use cases than phones. "Testing versus explaining." — Marco Arment / discussion theme: Used to contrast empirical testing with long theoretical debates, especially in the pirate eye patch segment. "Apple will do this for sure because it'll make them more money and it sucks for us." — John Siracusa: Summarizing the tension between Apple’s business incentives and customer experience.
Implications: Listeners should expect Apple to keep prioritizing iPhone economics while slowly improving durability and water resistance. The iPad may persist, but its future depends on whether tablets can become a truly necessary computing tier between phone and PC.
